Problem: redistribute bgp route into RIPv1 to solve vlsm issue without changing original prefix.
the connecting interface is a /24 the route is a /22
Method:
redistributing bgp route (that is in table) into RIP via route-map
creating a tunnel with a /22 subnet between the two routers and enabling rip on it
Desired result:
RIP should advertise that /22 over the tunnel and it should appear in the forwarding table since it heard the update for it over a /22 interface--even if it is a different major network.
It seems sound, but debug rip database does not show the route being advertised and thus it is not in the table. I can make the same redistribution (even without the subnets option) in OSPF and it gets propagated. So, I know it is not the route-map or the access-list. It must be something I'm not understanding about the classful restrictions associated with RIP, but I thought that this was a method of overcoming this obstacle.
pointers appreciated.
