By default, BGP does not
exchange IPv4 unicast routes
with any peer.
By default, no RR or RR client is
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).
By default, no routes are
redistributed into BGP.
By default, BGP does not filter
advertised routes.
By default, BGP does not filter
received routes.
