I have two routers connected over a third router that is emulating a frame-relay cloud.
I have set up lookback interfaces on the routers and am trying to use RIP to propogate these routes - summarised.
ROUTER A has the following lookback interfaces:
ip address 192.168.1.1 255.255.255.0
ip address 192.168.16.1 255.255.255.0
ip address 192.168.32.1 255.255.255.0
ROUTER B has the following lookback interfaces:
ip address 172.16.18.1 255.255.240.0
ip address 172.16.76.1 255.255.240.0
ip address 172.16.192.1 255.255.255.0
And this is the RIP configuration:
However, the routers are not exchanging the routes to the loopback addresses.
With the debug ip rip turned on, I can see that neither of the routers is even sending the loopback summary address of 192.0.0.0 or 188.8.131.52.
What am I missing here? It does work if I change the statements in RIP to reflect classful networks, i.e. e.g. 192.168.1.0.
Thanks in advance.
