MY CCIE JOURNEY

simple steps to follow ..

* those who want to install ubuntu linux can order their copy for free at

http://www.ubuntu.com/getubuntu

you can either download or request it .. i would ask you to do both of them ....

* check the compatability with your system most of the desktops should not have problems what so ever .. even all of the laptops are covered well except some of the wifi part

* as linux ships with many of the non commercial softwares you cant even play mp3 files .. for that you need enable repositories .. you can find the entire guide here

http://ubuntuguide.org/wiki/Ubuntu:Hardy

* downloading and installing is straight foreward for gns3 ... it should work well other wise browse any of the docs or blindhog ..

after you could install gns3 its all same from there on .... there is a package called compiz fusion which is rocking for eyes .. the guis effects are to bee seen by everyone who hadnt

any help let me know via mail

regards
raaki

my health is not supporting me these days as there is a climate change .. neverthless .. i have made some advancements ...

i have got craze for linux and installed a red hat 9 in my school days on a old compaq computer .. from then on there was some thing or other which was poking at me .. coming back ..

as i have already told you that i would increase my ram for gns3 soft run . but now i have changed my mind to postpone it .. the reason is linux

beleive me or not .. linux has a better management of ram and memory than windows which i used to use for previous labs ..

i have installed ubuntu 8.04 64 bit edition .. had some problems with wifi and vga stuff fixed all of the issues in these two days .. installed gns3 .. obviously not successful in my first attempt due to some of the mistakes but saw it now and posting it immediately ..

i could start upto 17 routers in gns3 with linux in hand .. dint done any lab on it though ... and observed memory ...

firstly the memory was at 919mb out of total 1.7gb availabe ram memory .. and swap memory was around 3.8 which is double the ram ofcourse ..

now i have installed 4 of routers and ram increased to 1100mb and from there on it stopped increasing even though i have increased the number of routers .. the reason being swap memory is taking over it now .

yes the ram memory increase stopped at 1100 mb and virtual memory began to increase . virtual memory = swap memory and so i could increase number of routers to greater extend without any system hang .

so i would recommend ubuntu for users who has a memory hang experiences with their pc's . also tried with dynamips .. but i couldnt do it for long ... as i am used to gns3 ..

so all in all instruments are sharper again for me ...

guday

today as mentioned went to prometric partner for the scheduled exam 70-113 which was offered free by microsoft and discovered that information cannot be retrieved from the server for this exam . i am dissapointed as i had put some quality time for the past 4 days and effort .. ne ways got to get down with cisco ... my apologies for giving you the advise to take the exam .. meet you redistribution lab

regards
rakesh

few updates from my side my university exams for this sem have been completed by today and still 3 more sems to go ... ;( and i have paused cisco side a little bit just because of one reasoni got a mail from microsoft website stating that there is a free exam on 70-113 if passed and present in first 3000 would walk away with 3 vouchers .. of course iam not that lucky nor in need of microsoft certs .. but just to attempt a international cert for free .. i have installed windows server 2008 and i must agree its rocking fast .. yes, it is running like dream ... superb effort from microsoft i should say .. i have scheculed from microsoft exam this monday so as i would prepare these two days and leave it off instead of wasting holidays as i need to concentrate on cisco stuff ... and also from the hardware part iam trying to upgrade my ram to 4gb for smooth gns3 run ... this is it . i will let you know how exam went .. i would recommend any one having free time to take this exam as it is of free of cost .. just a small advice .. for further details you can search for 70-113 and you will get to know everything .. guday

Setting the Clock and Timezone
------------------------------------

Given the last tip this one goes without saying. Set it as close to real time as possible and use GMT if you have multiple timezones for devices you manage or use the local timezone otherwise.

Very helpful.

Darby# clock set 1:18:00 November 18 2008
Darby# conf t
Darby# clock timezone EST -5
Darby# clock summer-time EDT recurring

Use show clock to verify.

Display an Interface Config
-------------------------------

sh run int f0/0

Now you can do even more:

sh run section router


Erasing an Interface Config
-------------------------------

Simple one but that may not be known about or easily forgotten in a pinch:

default interface f0/0

Works great it just wiped all configuration from that interace. Ready to start again. Kinda like Play-Do or Silly Putty but in a Router or Switch.

Setting the Terminal Length of a Router, Switch, or Firewall.
--------------------------------------------------------------------

24 lines ain't enough sometimes.

I backup configs a lot before and after I am doing things so... I don't like the page breaks that are arbitrarily assumed.

So...

term length 0 works on a router or switch and pager length 0 works on a PIX/ASA.

The default is 24, so...

"term len 24" sets it back to normal on a router/switch or pager length 24 on a PIX/ASA.

I find that a full screen is about 36 lines... but it may vary based on your screen's resolution.

Filtering the Output of commands
--------------------------------------

This is cool but gets even cooler once you begin to master regular expressions.

Here's some simple examples:

sh run begin route eigrp

sh run include ip route

sh ip interface brief exclude Down

I also use it alot when I'm hunting down a mac or ip address... Kewl stuff.

You can use regular expressions to get make if more grep-like...


Also remember show run section XXX works great too.

Do Command
----------------

This command allows us to "execute" commands while we are in configuration mode.

Darby(config-if) do sh run interface f0/0

We can use aliases and emulate the "Do Command's" functionality as well.

Alias Commands
-------------------

We can use this command feature to create our own commands.

alias exec s sh ip interface brief
alias configure s sh ip int brief (note this is so the same shortcuts will work in other modes on the device as well).

Only cause I find myself typing do out of context after I've been using it for a while.

Privilege Levels
------------------

This is a very useful tool for network management. By default all commands are either privilege level 0 or 15.

You are either poor or rich...

The privilege level command allows us the ability to create a few middle classes....


privilege level <0-15>

Darby(config)# privilege exec level 2 show
Darby(config)# privilege exec level 2 show ip route

line vty 0 15
privilege level 2

Assigns the default privilege level of 2 to vty sessions 0-15 for an example.

username Darby privilege level 2 password Darby

line vty 0 15
login local

Assigns the user Darby with a privilege level of 2 for another example. We also ensure that vty logins use the local database in this case.


Stopping "The Runaway Debug"

Plenty of ways to help solve this issue.

1. undebug all - make an alias for it like this

alias exec u undebug all

2. Use conditional debugging

debug interface f0/0

3. Filter the debug

access-list 1 permit ip 10.1.1.1 0.0.0.0

debug ip packet 1

Editing Access-lists
----------------------

Alway try to document when possible - use descriptions and remarks and names that are self-documenting.

Extended Access-lists permit us to edit the acl by line number.

No Service Configuration
-----------------------------

Speaks for itself.

Sometimes you'll find a device that is booting really slow and later find it is trying to boot from tftp somewhere...

Maybe you don't want your device to do this.

This can slow you down a lot. Really. A whole lot.

Hope these tips help you a bit.

Cisco IOS Tips and Tricks..

* this completed the eigrp revision and i will be back on redistribution lab 2 very soon ..or may start of with the revision of ospf or bgp depending upon my time availability .. after 24 th i will be surely after redistribution and will knock it off in two days

Eigrp Authentication:

* 3 parts to remember while configuring Authentication

* key creation and management

* Authentication mode

* assigning key to an interface

* key chain should be configured first and this is done under global configuration mode

* Create key

* Create key string , send lifetime , accept lifetime

* Info configured can be seen by issuing the command SHOW KEY CHAIN

* Next step is to apply it to an interface

* ip authentication eigrp 1 mode md5 ---> this is the authentication mode

* all constructed elements should be relevant and also they must and should be case sensitive with key strings and authentication modes being equal

Default Information originate and How to avoid it :

* In order to suppress the default routes , we can go into the router config mode of eigrp and issue the command as follows

* ROUTER EIGRP 1 ---> NO DEFAULT-INFORMATION IN


CREATION OF DEFAULT ROTUE:

* If we want to have a default route , we have more than one way to do it

* If we have a static route configured , redistribute the static route with a some of the default metric value

* Another way is to use the summary address in the interface level config mode to accomplish this task

* INT FA0/0 ---> IP SUMMARY-ADDRESS 0.0.0.0 0.0.0.0


Eigrp Load Balancing:

* By default eigrp loadbalances across 4 equal cost paths

* We can change the number of paths any where between 0-6 with the issue of MAXIMUM PATH command in router config mode

* For unequal load balancing we can use the VARIANCE COMMAND which ranges from 0-128

* This is done under router config mode
VARIANCE X --->it load balances between the routes which are x times more than the best one

* This is cost based load balancing sharing 1:x(will be done based on the variance level ) ratio of packet traffic

* If we want to alter this , this can be done under router configuration mode

* ROUTER EIGRP 1 ---> TRAFFIC SHARE MIN

* In this way the minimum cost will be preffered

* If we want to revert back to normal behaviour it should be done again in the router config mode
ROUTER EIGRP 1 ----> TRAFFIC SHARE BALANCED ----> defaults will be applied

* As a side note route tagging can also be used to acheive this task

EIGRP TIMERS :

* Update timer : rate at which updates are being sent

* Invalid timer: the time interval after which a route is declared as invalid

* Hold timer: how long the route is holded on depending on the other routes received

* Flush timer: the time after which the route is removed from the routing table

* Hello timer: hello interval defines how often hello packets are sentout which are used to establish neighbouring relationships

* On t1 or faster interfaces the dafault value being 5 secs and on nbma or slower links the timer value being 60 seconds

* If we want to change the timers , it should be done both ends and also this behaviour also applies to bandwidth command

* SHOW IP PROTOCOLS can be used to check the values

* The change should be done across the interface level
IP HELLO-INTERVAL EIGRP 100 15 --> this sets the interval to 15

* The same confiuration can be done for the HOLD time changes

* By default the hold time will be 3 times more than the hello timer

* Changing one timer will not change the other timer

* ACTIVE TIMER : this is used to minimize the effect of STUCK IN ACTIVE problem

* THIS CAN BE DONE ---> ROUTER CONFIG MODE ---> ROUTER EIGRP 1 ---> TIMERS ACTIVE TIME 180

SPLIT HORIZON:

* May arise with secondary/multipoint situations

* can be closed down under interface level configuration mode

* INT FA0/0 ---> NO IP SPLIT HORIZON EIGRP 100 ---> this disable split horizon

* We can also use VALIDATE UPDATE SOURCE command mostly done with secondary address in place

* ROUTER EIGRP 1 ---> NO VALIDATE UPADTE SOURCE

* you may land up with an error in times "ROUTER NOT ON COMMON SUBNET"


EIGRP STUB ROUTING:

* CONFIGURATION IS DONE UNDER ROUTER MODE

* EIGRP STUB ---> can have different parameters

* receive-only , connected , static , summary all of them being obvious and the point is to redistribute



* also not all the config commands are from console line so of them may have hifuns (-) between them or not i just used them


regards
rakesh

Offset lists:

* Another way to adjust metrics

* No need to modify K-values

* Can be used to manipulate metric for one of the multiple routes pointing to the same destination

Configuration:

* Create an access-list

* Create an offset-list

* ACCESS-LIST 10 PERMIT X.X.X.X Y.Y.Y.Y

* ROUTER EIGRP 4
OFFSET-LIST 13 IN 160000 FA0/0

A metric of 16000 would be added and will replace the old metric which is calculated
Route-summaraisation:

* Turn-off summaraisation with no auto-summary command

* Done under the router eigrp process ROUTER EIGRP 1 ---> NO AUTO

* Interface level summaraisation (this is what we do when we go for manual summaraisation and should be done at interface level)

* INT FA0/0 IP --> IP SUMMARY-ADDRESS EIGRP 1 NETWORK MASK

* Immediately a routing update is sent out

* On local router a summary-address for null0 interface will be generated

* In newer ios images a D route will be generated

Bandwidth:

* Eigrp uses 50% of bandwidth by default

* This may lead to some of the miscalculations which are to be considered crucial in qos and traffic-shaping

* Serial-interface which is t1 line or greater will be considered as 1.5megs as default

* This should be modified with the help of the bandwidth command in the interface level

* Also bandwidth percentage can be controlled with the interface level ip bandwidth-percent command

* ip bandwidth percent eigrp 1 10 to modify the percentage to 10% under as 1

the points are scattered so please dont mind

* Eigrp may be termed as enhanced igrp . defined as hybrid with both distance vector and link state .. but to be precise may be termed as advance distance vector routing protocol out there

* It works on on local link multicast exchange 224.0.0.10

* Neighbor process or discovery is done with the help of exchange of hello exchage . neighbours are alive till hellos are exchanged

* For multicast exchange , all of the interfaces must be of multicast capable .. this includes atm / frame - relay concepts

* The neighbor discovery process is done via hello packets that are exchanged via multicast

* Eigrp offers multiprotocol support ip , ipx , appletalk

* Eigrp provides RTP RELIABLE TRANSPORT PROTOCOL . through this packets can be exchanged via unicast / multicast

* The point to remember is that Hello packets are not needed to be reliable

On to the algorithm and routing proc

* DUAL - diffusing update algorithm . responsible for processing , installing and maintaining routes

* Also has to offer list of routes for feasible successors and successors via next hop

* If no feasible successor is present , or route goes down Recomputation is done

* Recomputation is processor intensive and uses dual to see the neig relationships again

* Table in eigrp include NEIGHBOR TABLE , TOPOLOGY TABLE , ROUTING TABLE

* Neighbor table contains adjacent neighbors , how neighbors has been discovered , interfaces , hold time , neighbor id , transmissions

* Topology table . this is done by the protocol module .. ie if we are running eigrp under ip , the table will be populated by ip protocol

* This is the backbone . it contains all destination routes advertised by neigh , metrics , perfixed , list of neigh , and for each route there will be metric which is advertised

* The route with best metric will be forewarded to the routing table . it is termed as successor ie primary path

* Feasible successor more or less like a back up path . one path can have multiple feasible successors . if successor goes down it will replace by fs and for replacement no recomputation is necessary

NEIGHBOR OPTIONS IN EIGRP

* Neighbor table is dynamically built as it receives hellos from different neighbors

* SHOW IP EIGRP NEIGH can be used for viewing neigh , addr , int , neigh

* NEIGHBOR COMMAND is to statically specify neighbors and also should be specified with the interface with which it can be reached . this is used to establish unicast routing

neig 100.0.0.10 fa0/0

* The results can be seen by the SHOW RUN , SHOW IP PROTOCOLS

* SHOW IP EIGRP NEIGHBORS will not list it because you need to have neighbor command done on both neig routers

* PASSIVE INTERFACE cannot be done on eigrp as it uses multicast hellos and hellos are to be sent in order to have a neigbor relation ship

* If we are asked to configure a passive interface in eigrp a simple way to do is to configure DISTRIBUTE LISTS .

* Create an access-list denying all traffic and place in the router process with the help of distribute list

ACCESS-LIST 30 DENY ANY

DISTRIBUTE-LIST 30 OUT


MORE INTO SIMPLE CONFIS AND METRICS

* METRICS OR K VALUES bandwidth , load ,delay , reiablilty , mtu .

* SIA ERROR stuck in active . this is where when mentioned no fs can be found for the topology table . the problem is that it wont have any timeout period and sia packet goes on and on till it gets a yes or no reply from neigh . if the router is busy to respond to this sia packet more time will be taken for recomputation

* Three simple steps

enabling routing protocol

defining as number

giving network command

* ROUTER EIGRP 125
NETWORK X.X.X.X
NO AUTO ------------ to turn off auto summaraisation

* SHOW IP PROTOCOLS can be used to see timers , neigh , metrics

k-values can be seen here .

* A K VALUE IS A 32 BIT NUMBER / MODIFIER .. SO IF YOU CHANGE VALUE OF K OR INCREASE A K VALUE BY ONE IT WILL AFFECT HUGELY

* metric can be best viewed with show ip route command

* K-values can be modified with the help of metric weights command

METRIC WEIGHTS ALWAYS START WITH ZER0 AND FOLLOWED BY K1 . K2 , K3 , K4 , K5

DEFAULT VALUES ARE 1 0 1 0 0

BANDWIDTH , LOAD , DELAY , RELIABILITY , MTU

these are few of the updates from me .. need to update blog ..it is lagging like hell lol ... i will continue with the eigrp revision part ..

good luck at what ever you do and also wish me

regards
RAKESH

setting a default route will do the trick

next step is to redistribute two of the protocols for full connectivity

configuring passive interfaces in ospf

before that lets see a debug out put of rip

this is how we do it

leaving the networks 172.16.1.0 and 192.168.70.0 we can summarize all of 48 , 49 , 50 , 51



our summary is 192.168.48.0/22

lets implement our summary addr at r1

take a look at the routing table of r2

on r2 lets configure s2/0 in rip and l0 and s2/1 in ospf

config for r2

CONFIG FOR R1

my gns3 messed up so i had to reconfigure one of the routers in topology ..

router 1 and router 3 will have full configs and router 2 will have initial configs

Learning Objectives

• Review configuration and verification of RIP and OSPF
• Configure passive interfaces in both RIP and OSPF
• Filter routing updates using distribute lists
• Redistribute static routes into RIP
• Redistribute RIP routes into OSPF
• Redistribute OSPF routes into RIP
• Originate a default route into OSPF
• Set a default seed metric
• Modify OSPF external network types
• Configure summary addresses

Scenario

Two online booksellers, Example.com and Example.net, have merged and now need a short-term solution to interdomain routing. Since these companies
provide client services to Internet users, it is essential to have minimal downtime during the transition. Example.com is a small firm running RIP, while Example.net has a somewhat larger network running OSPF. The diagram identifies R2 as the router that will bridge the two networks. Since it is imperative that the two booksellers continuously deliver Internet services, you should bridge these two routing domains without interfering with each router’s path through its own routing domain to the Internet. The CIO determines that it is preferable to keep the two protocol domains pictured in the diagram during the transition period, because the network engineers on each side need to understand the other’s network before deploying a long-term solution. Redistribution will not be your long-term solution, but will suffice as a short-term solution. Configure the topology above in a lab to verify the short-term solution. In this
scenario, R1 and R2 are running RIPv2, but the 172.16.23.0/24 network between R2 and R3 is running OSPF. You need to configure R2 to enable
these two routing protocols to interact to allow full connectivity between all networks.

this is how you execute the prefix list command

the requirement was that sanjose2 should not send updates or network info about 199 network

advertise network 199.9.9.0 on sanjose 3 and see the results both on sanjose2 and sanjose1

there are two things two keep in mind here while configuring

first of all , the primary requirement of this lab was to advertise all of the networks with the help of rip routig protocol , except 199.9.9.0 network

this is done on purpose to test the route reflector purpose

config for sanjose3

config for sanjose2

Learning Objective

In this lab, you will configure IBGP routers to use a route reflector and a simple
route filter.

Scenario

The International Travel Agency maintains a full mesh IBGP network that has quickly scaled beyond 100 routers. The company wants to implement route
reflectors to work around the full mesh IBGP requirement. Configure a small cluster and observe how BGP operates in this configuration. Use IP prefix filters
to control the updates between IBGP peers.

router configs to follow

a small advice from me guys/gals ... who ever practicing labs no matter how large or small they may be .i got a great idea last night

use camtasia studio screen recorder for that .. yes you will anyways do the lab right ..so why not just record the lab with your moves and stratagies in your own language or english up to you and see them as revision part ...

it has proved to be effective ..as atleast while revising you can see where you went wrong .. or what the plans were ... this wont take any of your time as the recording goes on and there is nothing you should do except pressing a record button and carry on with your work .. see at the amount of distractions you will get .. i poked several of the websites some of the downloads and what not as greatest distraction tools .. my sincere and effective advice .. if you feel like doing please go ahead and start the one

regards
RAKESH

the next was creating a default network to 192.168.100.0 network .. this can be done as below .. also see the routing table for the changes

the first requirement is that the serial link between sanjose1 should be used rather than sanjose2

here are the configs for that .. i created route maps and applied it on the neig statements

take a look at the values of metric and local pref

as always these are the final configs

config for sanjose 1

Learning Objectives

In this lab, you will configure both IBGP and EBGP. For IBGP peers in this lab to correctly exchange routing information, the next-hop-self command must be
used along with the Local-Preference and MED attributes. This is to insure that the flat-rate, unlimited-use T1 link is used for sending and receiving data to and from the AS 200 on ISP. The metered T1 should only be used in the event that the primary T1 link has failed. Traffic sent across the metered T1 link offers the same bandwidth of the primary link but at a huge expense. Ensure that this link is not used unnecessarily.

Scenario

The International Travel Agency runs BGP on its SanJose1 and SanJose2
routers externally with ISP, AS 200. IBGP is run internally between SanJose1
2 - 17 CCNP: Building Scalable Internetworks v5.0 - Lab 6-3 Copyright © 2006, Cisco Systems, Inc
and SanJose2. Your job is to configure both EBGP and IBGP for this
internetwork to allow for redundancy.

this lab has just took me my a** off .. yes i mean it . not that its that a difficult job or practice to have but i was making mistakes of configs or ips or as numbers what not .. i was not in my mind and was wasting time until i decided to knock it off and do it afresh instead of debugging it for mistakes ...

strange experience till now as i was enjoying all my labs without much difficulty

all the configs are straight foreward and doesnt require and explanations .. configuring ibgp and ebgp relationships is quite simple .. the only thing to remember is update source and next hop self commands

the tasks in this lab is to play with local preference and med operators ... having said that , the following are the configs to follow

and by the way i realised the beauty of extended ping now . a special thanks goes to pappyaar for answering and clearing things off along with compy

here are the configs and topology to follow

and now completely a u turn topic for me .. regular expressions .. not covered extensively ... but the condition is that no routes with as-number 100 must be in router cust routing table .. this is done as below

i know only two things for now

^number$ -- must begin and end with that number

.* -- all of the values just like (permit any as we need to give it as this is based on access-list and implicit deny follows it )

with everthing configure primarily here is how the bgp routing table looks like

Learning Objective
In this lab, you will use BGP commands to prevent private AS numbers from being advertised to the outside world. You will also use the AS_PATH attribute to
filter BGP routes based on their source AS numbers.

Scenario

The International Travel Agency’s ISP has been assigned an AS number of 300.This provider uses BGP to exchange routing information with several customernetworks. Each customer network is assigned an AS number from the privaterange, such as AS 65000. Configure ISP to remove the private AS numberswithin the AS_Path information from CustRtr. In addition, the ISP would like to prevent its customer networks from receiving route information from International Travel Agency’s AS 100. Use the AS_PATH attribute to implement this policy.

router configs to follow

and now to verify it we can create a loop back on isp1 and we should not advertise it to bgp .. still as it has a default router our sanjose router should ping it from default gateway

now next part of the configuration is

think that isp1 and isp2 are the two providers for sanjose network and sanjose wants to use isp1 as the preffered router and isp2 as the backup route ..

how do you do this

simple configure two static routes and in that give one of the preffered one low metric hence the problem will be solved . it can done like this

and also can you see anything like default route set or default gateway set for the sanjose network ...

this is the original routing table of sanjose network

this is as simple as childs play ... first create and access-list and deny 12 traffic and donot forget that there would be an implicit deny so be careful to permit all of the statements ...

now from here on we can have some interesting part ...

let us see the routing tables of all the three routers

these are the configs and tables from isp2

this part of debug out put is from the isp1 router

still not configured on either ends just on one router

this is the initial debug out put

before eshtablishing neigh peerings lets turn on debugging for the detailed effect of bgp

config for isp1

In this lab, you will configure BGP to exchange routing information with two Internet Service Providers (ISPs).

Scenario

The International Travel Agency relies extensively on the Internet for sales. The company has contracted with two ISPs for Internet connectivity with fault
tolerance. You need to configure BGP, which runs between the San Jose boundary router and the two ISP routers.

following are the router configs to follow

done with the redistribution part and route-maps and onto lab-1 .. the following are the router configs and lab topologies .. i have to admit that ts is damn boring in route redistribution , but also had important points so i would advice atleast see it once as you would get many real world tips ...

ompelted bgp from ts part and also from cbtt . looking foreward for route redistribution and nat / route-map from ts .. after that lab work to follow there are 14 labs i guess with bgp 4 redistribution 5 and route map 4 -- one on dhcp server which will be done last

i have to admit that ts is little boring and took so much time for me to complete .. but it has details and its real good ... this the part one or phase of the studies so no notes jotting business till now ... after iam done with the labs i would also post some of the important points ...

and also little offtopic is that went to quantam of solace and i have to give it a rating of 5/5 as iam a bond fan ...


thinking to complete the redistribution part today at any cost from ts and by tomorrow route-maps part ... after that within a week i would complete the multicast and ipv6 part with a small topic left with dhcp service ... and i should be offically done with lab work and ts and cbtt by nov 20 .. these are just the goals of mine as of now .. but my external exams are approaching real fast and they are scheduled from nov 11 ... holy shit

any ways catch you with redistribution part and the way it is dealt in both vendors

done with cb.t nuggets and onto train signa.l ... decent amount of info is available in cb.t nuggt.s ccnp series ... and t.s have got it all i guess ...completed and only one part of video out of four ... yet to do labs .. what i have learnt is

attributes --- 6 of them weight and local pref are being imp

route maps --- beautiful techniques on filtering the routes

debug bgp commands and their verification

show commands and their details

2 of the labs from nugget.s


catch u with the updates and also there are my sem lab exams gng on which is pain in a55..yes boring and time consuming dirty lab exams ... need to work with mercury and fluids along with carpentry work , soft mud for casting and other process ....pain i need to study them all .... and as opposed to scott morris ...there's everything i can learn the day before for my college lab exam ..hehe

as i have already mentioned labbing of is-is will be done at last of the bsci course ...

started of with monster .... bgp

started off with cb.t nuggets and i should admit that it really vast in its approach and also i am enjoying it and feeling real easy ... the entire of the protocol is masterly designed and implemented starting from scratch and i could understand the points the mentor jermy was mentioning ...

labbed and could see the results ....

some of the points of my interest are

slow convergence / start


no exchange of updates between ibgp's ----------- beautiful point some how i feel that this concept is great

neighbour and network statements with update source and multihop and also self commands in place


still studying attributes and implementation ... and its way long to go... i have learned new way of approach from one the vendors out there and i try to implement the debugging and labbing approach with respect to that...

still to go with [productbanned] and two other vendors for bgp and after that it would take only few days to complete my bsci...after that a vigours revision schedule for two months and planning to take my exam in feb .... things started nice and cool at this stage ...

bring you with more updates and if possible the lab part of cbt.t nugget.s

i hope this is informative for you and i like to thank you for viewing

starting out with lab 3-4 in ospf ... its simple and similar to eigrp frame-relay lab ..not thing there much ..... i have seen is-is and left it for last ... i went after bgp and started the cbtt nuggets .. it will take three more days time to complete the bgp i guess from the video tutors

*is-is labbing will be done at the end of the course

any how here is the 3-4 ospf lab

Lab 3-4a OSPF over Frame Relay

Learning Objectives

• Configure OSPF over Frame Relay
• Use non-broadcast and point-to-multipoint OSPF network types
• Modify default OSPF timers

SCENARIO



You are responsible for configuring the new network to connect your company’seast branch and west branch through the company headquarters represented by loopback interfaces on each of the three routers. The physical devices havejust been installed and connected over Frame Relay hub-and-spoke. Configure OSPF to allow full connectivity between all departments.There will also be an Ethernet connection between East and West. This
represents a backup line given by a service provider.This topology may appear again in future labs, so save your configuration when you are done.

I WOULD JUST POST THE RUNNING CONFIGS AS THERE IS NOTHING HERE I COULD DOCUMENT AS THE PREVIOUS LAB ..EVERYTHING IS OF FRAME-RELAY WHICH IS DONE IN EIGRP SAME MAPPINGS OF IP AND DLCIS ROUTES ..SO NOTHING MORE SPECIFIC

POINT TO REMEMBER IS THAT

BROADCAST HAS A DR AND CARE SHOULD BE TAKEN THAT NO BDR GETS ELECETED SUING IP OSPF PRIOPRITY 0 COMMAND

POINT - POINT DOSENT NEED ANY DR OR BDR IT WONT ELECT AND DONT NEED ANY NEIG STATEMENTS TO CONFIURE .

GENERATING DEFAULT ROUTE IN OSPF


SIMPLE AND STRAIGHT FOREWARD

and there was a simple challenge to configure authentication of simple and md5 no two of the interface on r2 .. i did that if any one want check the running configs ... the documentation is taking more time than labbing lol


see you guys with frame-relay beast soon

I WENT AGAIN CONFUSED IN SUMMARAISATION WHILE CONFIGURING .... WHETHER TO USE AREA RANGE OR SUMMARY COMMAND .. USED THE OTHER AND COULDNT SEE THE SUMMARY SO AGAIN USED THE ONE WHICH I DINT USED AS SAW THE SUMMARY ADDRESS .. DONT COMMIT THESE SORT OF MISTAKES OR ILL CONCEPTS .. AFTER STUDYING DO WE NEED TO USE HIT AND TRIAL METHODS .. NO WAYS RIGHT ?



REMEMBER TWO SUMMARAISATIONS

INTER AREA SUMMARASIATION ---- MUST AND SHOULD BE DONE ON ABR --- DONE IS ROUTING PROC OF OSPF OBVIOUSLY AREA RANGE

EXTERNAL SUMMARAISATION ---- MUST AND SHOULD BE DONE ON ASBR --- DONE ON INTERFACE -- IP SUMMARY -- THIS IS ALSO OBVIOUS THINK IT ..

so here it is the interarea summaraisation we are looking so perform it on abr ... so now again .. we created a virtual link ... and abr in the sense you should go to r3 and dont commit mistake going to r2 ... yes now r3 is also an abr and we can summaraise on it .... be careful ..
