Step 3. Enter IPv4 MBGP address family view. 4. Configure the maximum number of MBGP routes for load balancing. Command ipv4-family multicast balance number Remarks N/A Not configured by default. Configuring a large scale MBGP network Before you configure this task, you must make peering nodes accessible to each other at the network layer. Configuring IPv4 MBGP peer groups In a large-scale network, configuration and maintenance become difficult because of large numbers of MBGP peers. You can configure peer groups to make management easier and improve route distribution efficiency. IMPORTANT: • To configure an MBGP peer group, you must enable the corresponding IPv4 BGP unicast peer group in IPv4 MBGP address family view. • Before adding an MBGP peer to an MBGP peer group, you must add the corresponding IPv4 unicast peer to the IPv4 BGP peer group. To configure an IPv4 MBGP peer group: Step 1. Enter system view. 2. Enter BGP view. 3. Create a BGP peer group. 4. Add a peer into the peer group. 5. Enter IPv4 MBGP address family view. 6. Enable the IPv4 unicast peer group. 7. Add an IPv4 MBGP peer to the peer group. Command Remarks system-view N/A bgp as-number N/A group group-name [ external | internal ] Not created by default. peer ip-address group group-name [ as-number as-number ] No peer is added by default. ipv4-family multicast N/A peer group-name enable N/A peer ip-address group group-name Not configured by default. Configuring MBGP community The COMMUNITY attribute can be advertised between MBGP peers in different ASs. Routers in the same community share the same policy. You can reference a routing policy to modify the COMMUNITY attribute for routes sent to a peer. In addition, you can define extended community attributes as needed. 198
