can't ping across networks

Dale_Bosley

Level 1

This is the basic layout of my network

CPS------192.168.0.10

Host

|

|

CPS------Fa0 int 192.168.0.4

Router---S0 int 192.168.100.1

|

|

JCWA-----S1 int 192.168.100.4

Router---S0 int 192.168.101.4

|-------fa0 10.6.18.4--host 10.6.18.10

|

|

CPTC-----S0 int 192.168.101.1

Router---Fa0 int 192.168.1.4

|

|

CPTC-----192.168.1.10

Host

I can ping from the Router and Host on JCWA to any of the other addresses on CPS and CPTC.

I can ping from CPTC router and Host to 10.6.18.4 and .10 also 192.168.100.4

I can ping from CPS router and Host to 10.6.18.4 and .10 also 192.168.101.4

But I cannot ping from the Host or router on CPS to CPTC router or host or vice versa.

What do I need to do to make this happen. I am running RIP on all 3 routers & advertising all networks.

Thanks for any help

Is it all /24 masks ? (or atleast same masks ). Also is it RIP v1, v2 ? Can you paste sh ip route from CPS Router, JCWA router and CPTC router ?

Sorry I was a bit vague, but this is a very simplistic network. they are all /24 and RIP v1

Here are the configs;

CPTC#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

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

Gateway of last resort is not set

thanks for your response

I can not deduce exactly what is wrong, but you could try to remove the static routes and just let the RIP converge and see what happens. I expect that you do not have any access-list configured also.

After playing around with a few ideas I got one to work. I made the default gateway on the CPS and CPTC router the JCWA router, and then put in a second DG with a route metric of 2 for the internet traffic, seems to work fine for now. Thanks for the help
