2. Enter BGP view.
3. Configure the MCE as an
EBGP peer.
4. Enter BGP IPv6 unicast
address family view.

Configuring IBGP between an MCE and a VPN site
To use IBGP between an MCE and a VPN site, you must configure a BGP peer for each IPv6 VPN
instance on the MCE, and redistribute the IGP routes of each VPN instance on the VPN site.
1. Configure the MCE:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP-VPN instance
view.
4. Configure an IBGP peer.
5. Enter BGP-VPN IPv6 unicast
address family view.
6. Enable BGP to exchange
IPv6 unicast routes with the
peer.
7. (Optional.) Configure the
system to be the RR, and
specify the peer as the client
of the RR.

By default, BGP does not
exchange IPv6 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 VPNv6 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).
