I understand one of the main purposes of using route reflectors to be for
providing iBGP peers a means to share iBGP learned routes. In my
understanding, BGP is built so that iBGP peers will not forward iBGP learned
routes, only eBGP learned routes. iBGP peering should be fully meshed so
routing information is not lost. In case you do not have a fully meshed
topology, route reflectors provide a means to override the default behavior
of BGP, allowing iBGP servers to forward iBGP learned routes to clients.
The senario you described:
R7--R1 R4
\ / \ / \
R2 R3 R5 R6
is a bit confusing to me. The point of route-reflectors is to allow the
sharing of iBGP learned routes with other iBGP neighbors without having a
fully meshed network. Redundancy is an option, but be sure you actually
have the physical redundancy to support your logical redundancy. I hope
that helps. Good luck.

Hi all.
Do you know if it is possible in BGP to have this configuration :
R1 has : R2 and R3 as RR clients
R4 has : R5 and R6 as RR clients
R7 has : R1 and R2 as RR clients
Thanks
