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. 2. Enter BGP view or BGP-VPN instance view. system-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 N/A 3. Create an IBGP peer group. group group-name [ internal ] By default, no IBGP peer group is created. By default, no peer exists in the peer group. 4. Add a peer into the IBGP peer peer ip-address group group-name group. [ as-number as-number ] To use the as-number as-number option, you must specify the local AS number. 5. (Optional.) Configure a peer group-name description description for a peer group. 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 peer group-name enable specified peer group. By default, the router cannot exchange IPv4 unicast routing information with the peers. To configure an IBGP peer group (IPv6): Step 1. Enter system view. Command system-view Remarks N/A 174
