MY CCIE JOURNEY

THIS IS THE TOPOLOGY OF BSCI SERIES IN CBT WHICH IS NOT EXACTLY SAME BUT I HAVE GIVEN SOME REFERENCE TO IT ....THIS IS FROM MY GNS3.. I WILL EXPLAIN THE BASIC TOPOLOGY ... IF ANY ONE THINKS THAT THEY NEED TO HAVE MY .NET FILE THEY CAN LEAVE A COMMENT I WILL GET BACK TO YOU..

Its important to note that i have used several shortcuts to make life easy and its recommended we work like that ..

for example see the following output


r0#sir
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

have you any time heard of a command known as "sir"

sir = show ip route...

instead of using the entire thing i have created the alias ...

so following post will be explaining some shortcuts like this and my usage if you find anything difficult comment below i will get back to it .
