Hi all,
We have three routers with full mesh ibgp peering with full routing table. We Are adding the new route reflectors on same as for all routers but we have to avoid the disruption of routing table and garant service. The question is: can I use rr and full mesh all together adding the rr peering on all full mesh routers ?
Thanks

Hi,
It is usually full mesh or use a route reflector. If your goal is to deploy RR without interruptions you can make the new router RR and have the other 3 peer with RR. Once that is completed, you can tear down full mesh connectivity. Do this during on outage window and not production.

Hello Isacco,
yes you can the reflected advertisements will not be preferred over the direct advertisements exchanged over the direct iBGP sessions between the three routers, as the first ones have BGP cluster-list attribute set.
Hope to help
