Re: why exactly, route reflector clients can't have ibgp connect

the routing update will never be forwarded to another IBGP peer by a RR client as iBGP is working.

(in fact it's what the RR workaround).

Re: why exactly, route reflector clients can't have ibgp connect

hi, thanks for your reply but looks like there's some misunderstanding here. my question is not what route reflector does. i know what it does is to work around ibgp update rule(split horizon). my question is why can ibgp peers which are rr-clients at the same time can't have ibgp peering with each other without no bgp client to cilent reflect( if i remember the command correctly).

thanks for you reply in advance

Re: why exactly, route reflector clients can't have ibgp connect

Hi

Did U manage to get an answer , if yes pls poste it as i am interesting to know the reason .

This case is indicated in "Internet Routing Architecture" book page 422 stating that in case

we have full iBGP meshing within a RR cluster it is recomended on the RR to turn off reflecting route

learned from a client to other client's (using no bgp client-to-client reflection) to avoid potential problems . Unfortunately the book did not descripe

what type of pblm and why .
