I built this and here are the results.
access-list 1 permit 201.43.16.0 0.0.0.255
These combo's worked:
1. router rip
distribute-list 1 in
2. router ospf 10
distribute-list 1 out
3. router ospf 10
distribute-list 1 out rip
These combo's didn't work:
1. router rip
distribute-list 1 out
2. router rip
distribute-list 1 out ospf 10
This is my conclusion from these results:
Rip doesn't actually hand off routes to ospf. ospf
looks in routing table to see what routes where placed
there by rip (redistribue rip command) and then
decides weather or not to advertise them based on
whatever filters are in place.
