You should be able to ping from router to router without too much problem.
However, from workstation A to B will not work because the Time To Live will
be exceeded. This is a known problem when redistributing RIP into IGRP where
the potential for a routing loop exists. For now just disconnect the straight
through cables on Ethernet 0 on both ritchie and ken. This will eliminate the
routing loop problem. Relax. Remember RIP takes a while to converge so you
might not see the routes or be able to ping for a few minutes. Also, clearing the ip
routes a few times couldn’t hurt either:
dennis#clear ip route *
dennis#clear ip route *
dennis#clear ip route *
dennis#clear ip route *
ritchie#clear ip route *
ritchie#clear ip route *
ritchie#clear ip route *
ritchie#clear ip route *
ken#clear ip route *
ken#clear ip route *
ken#clear ip route *
ken#clear ip route *
thompson#clear ip route *
thompson#clear ip route *
thompson#clear ip route *
thompson#clear ip route *
6. Once we have done this then now we can see how this affects our ip routes. On each
router you will see:
dennis#sh ip route
Codes: C - connected, S - static, I - IGRP, 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, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
U - per-user static route, o - ODR
