Command Remarks
4. Create and enter BGP IPv6
unicast address family view.
address-family ipv6 [ unicast ] N/A
5. Enable IPv6 unicast route
exchange with the specified peer
or peer group.
peer { group-name | ip-address }
enable
By default, BGP does not
exchange IPv6 unicast routes
with any peer.
6. (Optional.) Configure route
redistribution.
import-route protocol [ process-id
[ med med-value | route-policy
route-policy-name ] * ]
A CE must advertise its VPN
routes to the connected PE so
that the PE can advertise them
to the peer CE.
Configuring IBGP between a PE and a CE
Use IBGP between PE and CE only in a basic IPv6 MPLS L3VPN network. In networks such as inter-AS
VPN and carrier's carrier, you cannot configure IBGP between PE and CE.
1. Configure the PE:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Enter BGP VPN view.
ip vpn-instance
vpn-instance-name
Configuration commands in BGP
VPN view are the same as those
in BGP view. For details, see
Layer 3—IP Routing
Configuration Guide.
4. Configure the CE as the VPN
IBGP peer.
peer { group-name |
ipv6-address } as-number
as-number
By default, no BGP peer is
created.
5. Create and enter BGP VPN IPv6
unicast family view.
address-family ipv6 [ unicast ] N/A
6. Enable IPv6 unicast route
exchange with the specified peer.
peer { group-name |
ipv6-address } enable
By default, BGP does not
exchange IPv6 unicast routes
with any peer.
7. Configure the CE as a client of the
RR.
peer { group-name |
ipv6-address } reflect-client
By default, no RR or RR client is
configured, and the PE does not
advertise routes learned from the
IBGP peer CE to other IBGP
peers, including VPNv6 IBGP
peers. The PE advertises routes
learned from the CE to other IBGP
peers only when you configure
the IBGP peer CE as a client of
the RR.
Configuring an RR does not
change the next hop of a route.
To change the next hop of a
route, configure an inbound
policy on the receiving side.
