• Enter BGP view:
bgp as-number
• Enter BGP-VPN instance view:
a. bgp as-number
b. ip vpn-instance
vpn-instance-name
N/A
3. Specify devices in a
network as dynamic BGP
peers and specify an AS
number for the peers.

ipv6-address prefix-length
as-number
as-number
By default, no dynamic BGP peer
is specified.
4. (Optional.) Configure a
description for dynamic
BGP peers.
peer
ipv6-address prefix-length
description
description-text
By default, no description is
configured for dynamic BGP peers.
5. Create the BGP IPv6
unicast address family or
BGP-VPN IPv6 unicast
address family and enter
its view.
address-family ipv6
[
unicast
]
By default, the BGP IPv6 unicast
address family or BGP-VPN IPv6
unicast address family is not
created.
6. Enable BGP to exchange
IPv6 unicast routing
information with dynamic
BGP peers in the
specified network.
peer
ipv6-address prefix-length
enable
By default, BGP cannot exchange
IPv6 unicast routing information
with dynamic BGP peers.
Configuring a BGP peer group
The peers in a peer group use the same route selection policy.
In a large-scale network, many peers can use the same route selection policy. You can configure a
peer group and add these peers into this group. When you change the policy for the group, the
modification also applies to the peers in the group.
A peer group is an IBGP peer group if peers in it belong to the local AS, and is an EBGP peer group
if peers in it belong to different ASs.
Configuring an IBGP peer group
After you create an IBGP peer group and then add a peer into it, the system creates the peer in BGP
view and specifies the local AS number for the peer.
To configure an IBGP peer group (IPv4):
Step Command Remarks
