Step Command

Remarks

Enter system view.

system-view

N/A

Enter BGP view.

bgp as-number N/A

Enter BGP-VPN instance
view.

ip vpn-instance
vpn-instance-name

Configuration commands in
BGP-VPN instance view are the

same as those in BGP view. For

details, see Layer 3—IP Routing
Configuration Guide.

Configure the CE as the
VPN IBGP peer.

peer { group-name |
ipv6-address } as-number

as-number

By default, no BGP peer is
created.

Create and enter BGP VPN

IPv6 unicast family view.

address-family ipv6 [ unicast ]

N/A

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.

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.

(Optional.) Enable route
reflection between clients.

reflect between-clients

By default, route reflection
between clients is enabled.

(Optional.) Configure the
cluster ID for the RR.

reflector cluster-id { cluster-id |
ip-address }

By default, the RR uses its own
router ID as the cluster ID.
If multiple RRs exist in a cluster,
use this command to configure

the same cluster ID for all RRs in

the cluster to avoid routing loops.

Configure the CE:
