Hi,
I don't think you have given us sufficient info to discuss this,
i.etopology, however if I understand the task correctly, this is to do
with not
having to redistribute ospf into rip. Since r5, r4 and sw2 are already in
rip, they all know the rip routes, therefore why filter? It seems
unnecesary...r5 knows about the ospf routes and injects a default into rip
so that r4 and sw2 have reachability to the rest of the network.
Also r4 will load balance to destinations in the ospf domain based on the
default, but needs an offset-list so that the default seen by r5 and r2 has
the same metric.
Regards,
Elias
