HP 6125XLG - Configuring a BGP Peer Group

174
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
1. Enter system view.
system-view N/A
2. Enter BGP view or BGP-VPN
instance view.
• 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. Create an IBGP peer group.
group group-name [ internal ]
By default, no IBGP peer group is
created.
4. Add a peer into the IBGP peer
group.
peer ip-address group group-name
[ as-number as-number ]
By default, no peer exists in the
peer group.
To use the as-number as-number
option, you must specify the local
AS number.
5. (Optional.) Configure a
description for a peer group.
peer group-name description
description-text
By default, no description is
configured for the peer group.
6. Create and enter BGP IPv4
unicast instance view or
BGP-VPN IPv4 unicast
instance view.
ipv4-family [ unicast ]
By default, the BGP IPv4 unicast
instance view and BGP-VPN IPv4
unicast instance view are not
created.
7. Enable the router to exchange
IPv4 unicast routing
information with peers in the
specified peer group.
peer group-name enable
By default, the router cannot
exchange IPv4 unicast routing
information with the peers.
To configure an IBGP peer group (IPv6):
Step Command Remarks
1. Enter system view.
