Step
1. Enter system view.
2. Enter BGP view.
3. Configure the MCE as an
EBGP peer.
4. Enter BGP IPv6 unicast
address family view.
5. Enable BGP to exchange
IPv6 unicast routes with the
specified peer.
6. Redistribute the IGP routes
of the VPN.
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.

N/A
By default, no BGP peer is
configured.
N/A
By default, BGP does not
exchange IPv6 unicast
routes with any peer.
By default, no routes are
redistributed into BGP.
A VPN site must advertise
IPv6 VPN network
addresses it can reach to the
connected MCE.
Remarks

N/A
By default, no BGP peer or

N/A
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).
