Hello,
I am attaching a copy of "SH ip Routes" from two routers.
The problem, router2 cannot ping router 1, WHY!!!

Configs:

Router1#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, 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 10.20.0.165 to network 0.0.0.0

S 172.16.0.0/16 [1/0] via 10.20.0.58
67.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 67.151.48.156/30 is directly connected, Multilink1
C 67.151.48.157/32 is directly connected, Multilink1
10.0.0.0/16 is subnetted, 6 subnets
C 10.20.0.0 is directly connected, FastEthernet0/0
S 10.40.0.0 is directly connected, Multilink1

what address are you trying to ping? can you ping vice versa or is it just a one way thing?
 
show a brief topology and a show run from both routers.

Normally this is because there is no route back.

Hello,

Router 1 IP is 10.20.0.1
Router 2 IP is 10.40.0.1

Router1 can ping router2 and get a reply
Router 2 cannot ping router 1 Success rate is 0 percent
 
Post a sh run from both routers. Since 1 can ping 2, then there is a route to AND from 1 and 2.
