MY CCIE JOURNEY

Hello everyone ... its been a while i wrote about my prep path .. it has also some thing to do with my exams going on and iam in a verge of creating / launching a website which will be uniqe .. so iam into learning the content management system joomla . so had to stop my prep and concentrate on making the website look and feel good ...


Presently we are a team of two members and the website concept is uniqe .. I need more of the elite members to join me and also aditionally to gain some rep in the community ...

anyways , joining in a team doesnt involve or doesnt require any one to any of the scripting skills / programming skills ... they just need to have good ability to pick some articles and choose the best of the articles ...

the majority of the concept being to make a free emag which will be available to all people with photos of our team members .. the website is official and no warez stuff which will make us proud to be part of the team

And lot of other goals and plans which cannot be disclosed as of now .. so , guys if you are interested and have some time to contribute please let me know at

raaki_88@yahoo.com

so the prep update will be stopped for another week or so .. any ways got to go and work on it ..

good day

regards
rakesh

Started with ospf and done with video 1 from cbtt nugets ... also wanted to revise and go from the ground level so went on with the part 1 of laura chappels course and started with arp .. i have got so much of stuff but never had fun using them .. iam utilising them now a days boy iam happy ..

so to start of with ospf nothing complicated to explain or revise until the other two videos

on to laura chappel well the concept was on arp and now i could understand what is arp , why it cannot be forewarded accross routers etc

main concepts involve

gratituos arp

proxy arp

and arp headers

gratituos arp is nothing but a arp packets which checks and validates the ip address given to the system is not given for any other system . this is done by sending a arp packet which contains its own ip address , so if a duplicate system is present it responds to it so that it can be corrected

proxy arp if we know about router converting or routing different netwoks its the same , the router gives its own mac address of the interface without forewarding the broadcast as arp is based on broadcast

arp headers dosent contain any info on protocols such as tcp udp and ip headers so it basically cannot be read by devices which looks for ip headers


this is to sum up

It's been a while .. i went on a holiday and hell i did enjoy a lot ... hehe cant reveal it though ... any ways i wanted to inform you with the left out labs from foundation gap and also holiday thing but couldnt as sadikhov was down and i couldnt write them down ..

our college has given us holidays for a week and in the mean while we planned for a holiday spot which is full of green stuff and beach to surround ... ohh i want to work as a fisher man over there ... holy hell ...

great ...

done with lab 4 and lab 5 from foundation gap

lab 4 :

loadbalancing .. ---> nothing great in this ---

covered commands -- > variance , traffic share count

timer manipulation .. --- > sia -- x minutes , disabling sia --- > can be done from router config mode > timer ?

lab 5:

authentication :

mode : mds5

key - chain config ...

on to ospf revising cbt.t as need a good amount of revision and should be strong at concepts as we dont know what else can change in near future

Hai all , me and one of my pals named darlord (:0 alias exec darklord duplicatename) thought of building a minor cluster .. The idea was started by him and i downloaded and installed it .. and quick review

what is a cluster?

well iam not into clustering so i would define that its a group of computers connected and when booted with a cluster operating systems unites their resources and become one computer

In simple words :

consider two computer connected via a ethernet cable .. boot with cluster operating system and they will load balance and share the tasks

How did i do that ?

Well its a child play till now ... the best thing is labbing and for any thing any everything we can lab on vmware ..

The cluster operating system name is "cluster knoppix" a knoppix distribution .. feel free to google only 600 mb of cd

next create two vm's with "other linux 2.6.x" kernel and give the iso path to the cd rom in vmware and bingo you cluster is already booting ..


to make some sense in what iam talking see this screen shot



























now did you see two of the ip's of the vm's which has cluster knopppix os and console message "cluster has 2 members " ..

How does this help us ?


Dont you work with gns3 ...? ofcourse the answer is yes .... so when you happen to have some old computers and the unused ones or let us say you wanna add some power .. boot with cluster and bingo they share you cpu power and also efficiency

This is the structural note pad i have been following hope this helps

its so flexible and any time you can change and write down any thing .. it fast and typo free

to the ones who still wondering how can this be used to speed up our things ... theres nothing .. let us say you have started all of the routers and want some
good aliases just copy and paste directly the initial configs section .. everytime it stops at hostname so that you can configure :whew ingenious :lol:

done with lab 3 summaraisation and advanced summaraisation

as always everything is cool and new point / concept "leak map"

Configuring leak-map option allows us to advertise a component route (one or more specific networks of a summary route) that would otherwise be
suppressed by the manual summaraisation .

Three rules :

If the leak-map is configured to reference a route-map that does not exist, only the summary route is advertised and the more specific routes are
suppressed

If the leak-map is configured to reference a route-map and the route-map is referencing an access-list that does not exist , then the summary routes and all
the specific routes are advertised

If the leakmap is configured to reference a route-map and the route-map matches and acl , all the permitted networks b the acl will be advertised along with
the summary route




for example we have

we have a summary address 2.2.4.0/22

1. int fa0/0
ip summa eigrp 100 2.2.4.0 255.255.252.0 leak-map rakesh---------------------> (rakesh is the name of the route-map which is not configured)

in this case only summary route is advertised which will be equal to the commands output "ip summa eigrp 100 2.2.4.0 255.255.252.0"

2.

route-map rakesh permit 10
match ip address 77(----------------> acl is not configured)
int fa0/0
ip summa eigrp 100 2.2.4.0 255.255.252.0 leak-map rakesh---------------------> (rakesh is the name of the route-map which has no access-list)

in this case all of the specific and summary routes are advertised i,e

2.2.4.0
2.2.4.0
2.2.5.0
2.2.6.0
2.2.7.0

3.

both acl and route-map are configured

access 66 permit 2.2.6.0 0.0.0.255
route-map rakesh permit 10
match ip address 66

int fa0/0
ip summ eigrp 100 2.2.4.0 255.255.252.0 leak rakesh

this would advertise summary address and address we wanted to permit/ deny in the acl .. look there is an implicit deny which is followed

this is what that i found interesting ...

i need more clear understanding !!! in what sense ? well iam not happy with the output .. first of all what is the use of leak-map .. next ok that is general sense of the question ... but it is behaving differently for different set of rules .. how does it allow / deny packets or how does it work ... so on ...? iam gonna post this question and will let you know
