Hi,
>From your discription of the problem, 200.100.100.0/24 is not synchronized
at R4. The reason is that for IGP (ospf), this network is learned from
Router 2 (it is an ASBR) (not Router 3), while for BGP, it is learned from
Router 3 not Router2. So according to BGP/IGP synchronization rules for
OSPF/BGP, the network should be learned from the some Router, otherwise it
says not synchronization.
Exception for configuring R3, R4,R5 as BGP Confederations, actually I don't
know what is the solution of this problem.
If someone knows any other ways, please tell me as well.

Regards,
Joe
