system to be the RR, and
specify the peer as the client
of the RR.

configured.
After you configure a VPN site as
an IBGP peer, the MCE does not
advertise the BGP routes learned
from the VPN site to other IBGP
peers, including VPNv4 peers.
The MCE advertises routes
learned from a VPN site only
when you configure the VPN site
as a client of the RR (the MCE).

Redistribute
remote site
routes advertised by the PE
into BGP.
import-route
