Configuring a VPN Routing and Forwarding Instance in BGP
determine VPN connectivity and the label value to be used so the remote (egress) router can demultiplex the
packet to the correct VPN during packet forwarding.
The PE-PE, PE-route reflector (RR) iBGP sessions are defined to all PE and RR routers that participate in the
VPNs configured in the PE router.
Perform this task to configure PE-PE iBGP sessions and to configure global VPN options on a PE.
