[j-nsp] BGP RR in MPLS VPN

[Mounir Mohamed]

Dear,

Fom my point of view NO, becuase the RR will only forward the updates that
received from one PE to the other PE but in the same all the traffic toward
any destination that received from the RR will take an LSP based on the
running IGP as the RR forward the updates attached with next-hop that equal
to the orginator (PE1or PE2) so finally PE1 will received network X that
attached with Next-hope PE2 so any traffic toward this destination will
forward to PE2 ip addres which is learned via IGP, so the LSP will be
created to path through the P router as LSR not as RR.

I hope that help.

Best Regards,
Mounir Mohamed
