Configuring A Bgp Peer Group - HP FlexFabric 12900E Series Configuration Manual

Step
4. (Optional.) Configure a
description for dynamic
BGP peers.
5. Create the BGP IPv4
multicast address family
and enter its view.
6. Enable BGP to exchange
IPv4
information used for RPF
check with dynamic BGP
peers in the specified
network.

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
instance view and specifies the local AS number for the peer.
To configure an IBGP peer group (IPv4 unicast address family):
Step
1. Enter system view.
2. Enter BGP instance view or
BGP-VPN instance view.
3. Create an IBGP peer group.
4. Add a peer into the IBGP
peer group.
