Subject: BGP-OSPF
I have a BGP route reflector with 2 clients. Also a non client peer with the
RR.
The 2 clients are peering with an EBGP peer themselves. When I do
redisribution
on the RR into OSPF the routes from the non-client are redisributed but not
the
routes from the clients.
When I do a "sho ip route x.x.x.x" it says it is being redistributed into
OSPF
but it isn't, nor does it make it to the OSPF database. Sync is disabled and
I
have tried bgp redistribute-internal on the RR.
I have looked through the archives and saw a couple of threads on this but
no
answer as to why.
Is this normal RR behavior?
Thanks

I don't know if this will help but ONLY the BGP routes marked as Best Routes
in the BGP table will be redistributed.
NEW
Sure, I understand that part of the issue. These routes are in the route
table
and are best bgp routes. That is the best route from the RR clients.
They will not however redistribute into OSPF.I'm not using any route map for
the
redistribution into BGP. Here is BGP and OSPF DB's and partial IP
