WHat do u maen by adding network statement on spokes.
How is the Loops back interafces are advertised to BGP. Redistribution or
some thing else.

Subject: BGP and OSPF synchronization
I have 3 routers in a frame relay hub and spoke ospf configuration.
The ospf is working fine and I have set the router IDs to the router number.
R1 is 1.1.1.1 etc.
r1 ---------r5-----------r2
I have configured BGP in AS 13 on all the routers with r5 as a
route-reflector to both r1 and r2. Next I add a loopback on r1 and r2 and
include them in OSPF. They are reachable everywhere. I then add the loops
into BGP. When they get to R5 they are unsync because of the OSPF/BGP
router ID issue so I change the router IDs on R1 and R2 to match OSPF and
hey presto R5 syncs the loopbacks.
Now when I look at the spoke routers even though they get each others
loopbacks into their BGP tables they have marked them as unsync because they
are sourced from R5 for BGP and from the other end router for OSPF. Another
RID mismatch.
I can overcome this by simply adding a network statement for the unsynced
prefixes on each spoke router.
Is this a valid solution to the problem ?
The whole scenario is just a test to see OSPF/BGP interactions.
Thanks, Stephen.
