Routing issue

Unanswered Question
Jun 18th, 2007

I have a point to point t-1 that is currently working for traffic betweeen 192.168.0.0 and 192.168.100.0 (remote site)

I now neet to also route traffic from 192.168.51.0(remote site) and 192.158.50.0. The physical connection to this subnet is there and working and i can ping from both router interfaces but any traffic beyond that times out.

Here are the router configurations.

1) I recommend removing those static routes you have on both routers. RIP should take care of the networks you want to advertise.

2) Remove those ip access-group under the interfaces. You don't have any corresponding ACL.

Hi,

You should have a route for the ".100" and the ".51" on the local router to the remote ip of the p-to-p "192.168.254.2", and vice versa on the remote router (2 ip routes for ".0" and ".50" back to the wan ip of the local router "192.168.254.1") and not the opposite.

P.S RIP should do it !! you won't be needing static routes.

HTH,

Mohammed Mahmoud.

I have checked the configs that you posted and they mostly look good to me. I do note that all of the FastEthernet interfaces apply an access list called any to outbound traffic but that access list does not show up in the configs that you posted. It seems unlikely that it is the cause but it would be helpful to know what is in that access list.

From the configs it looks to me like all the networks/subnets should be in the routing table and things should work. Perhaps you can be a bit more specific about what is not working. Can end stations in 192.168.0.0 network access stations in 192.168.51.0? I would make a guess at this point that it may be an issue with configuration of default gateway on the end stations. One way to check this would be to do an expended ping from your router. In the extended ping specify the destination of the ping as 192.168.51.1 and specify the source of the extended ping as FastEthernet0/1. This will check to be sure that routing between the new networks/subnets is working ok on the router.

My take on this:

1. Remove the static routes to the Fa0/0 and Fa0/1 interfaces. They're unnecessary IMHO.

2. Check if the hosts on the other network that you're trying to ping has its firewall turned on and if it's blocking ICMP.

3. Post the output of sh ip route from both routers.

I removed the static routes (thanks for that)

thanks for all lthe help
