MY CCIE JOURNEY

hai all .. had a bad i net connection so couldnt upload any thing from the labbing part for yesterday .... i dont know when my i net flaps off .. so let me quickly spend my time here ... before gng on to the labs with ospf (2 labs) i will let you know what i had done last ...

it's the IS-IS protocol ...

the protocol is real simple and easy to configure ...

i had seen cb.t and train.signal and both of them had different points to offer ... over all is is is really simple and piece of cake to configure ...

the terminology is quite different ..but overall the id system and the routing proc is similar to ospf ...

only one bit to explain that is the net id

net id is similar to router id in ospf .. to understand primarily.. the point to remember while configuring net id is simple

net id has --- 3 fields

first field -- type of device -- always 00 for a router so .. as in this case in cisco systems it will be 00 ... ios alerts when wrongly configured ..

second field is ---- system id --- 6 bits or 12 digits --better to have a similar number or mac number upto you -- let us say for r4 : 4444:4444:4444

third field is the area id ----remember two things for exam purpose : 49 and 4 digits ----

49 -- significance of 49 is that it is like a private address in this osi model

and four digits ... simple way ..if you have area 1 --- name it as 0001

four digits are compulsory .. similarly for area 20 --- 0020

so ...

here is the way you write net address
