Routing RIP Protocol

[mario.milhazes]

I have two routers conected with 3 serial links:

- 56Kbps

- 12Kbps

- 512Kbps

I also have Rip going on on the 3 serial interfaces.

All the links have the same distance, 1 hop.

My question is how can i influence in the router choosing the best route using this routing protocol.

Can i change the hop count of the other routes to a bigger value, so that the router will chosse the route with only 1 hop?

Thanks

Hello Mário,

you could configure an offset-list under the RIP process to increase the metric of the routs you do not want to use.

Let´s say you have three RIP routes:

192.168.1.0

192.168.2.0

192.168.3.0

and you want to prefer 192.168.1.0, you would configure an access list matching the routes you do not want:

access-list 1 permit 192.168.2.0

access-list 1 permit 192.168.3.0

and apply the following command under the RIP process:

offset-list 1 out 10

this would increase the metric of the matched routes by 10.

Or you can apply the offset to routes learned from a specific interface:

offset-list 1 in 10 Serial 0

Check the following link for the complete syntax of this command:
