WAN Routing: Lease Line

Unanswered Question
Mar 28th, 2007

I have 3 x 1841 routers.

Head Office

Router A: LAN IP: 192.168.1.1/24

Router B: LAN IP: 192.168.1.10/24

These two are connected via Cisco switch.

Branch Office

Router C connected via Lease Line (Serial Port) to Router B.LAN IP: 192.168.3.1.

Router C only knows Router B. All traffic out is forwarded to that router. Router A is the main one that has all thr routes to other networks configured.

How to configure routing such that:

1. All traffic from Router C is forwarded to Router A.

2. On Router A, what config to enter to route to 192.168.3.x network.

Thx

I have this problem too.

If router C has only 1 external connection and it is to router B then router C probably should have a default route configured which point to router B. It should look something like:

ip route 0.0.0.0 0.0.0.0

On router A you would want a route to the LAN of C which would probably be:

ip route 192.168.3.0 255.255.255.0 192.168.1.10

it sounds logical.

perhaps there should be another route on Router B :

ip route 0.0.0.0 0.0.0.0

any confirmation?

Yes that does sound logical. I assumed from your original post that it probably already did exist. If your comment that router A has routes for most networks then it is logical that router B and router C should have default routes pointed to router A.
