Configuring MP-BGP

Configuring MP-BGP

Multiprotocol BGP (MP-BGP) enables BGP to support IPv4 unicast networks, IPv4 multicast networks, and IPv6 unicast networks.

Pre-configuration Tasks

Before configuring MP-BGP, complete the following task:


  1. Run system-view

    The system view is displayed.

  2. Run bgp { as-number-plain | as-number-dot }

    BGP is started, the local AS number is specified, and the BGP view is displayed.

  3. Enter the corresponding address family view based on network type to configure BGP devices on networks.
    • Run ipv4-family unicast

      The BGP-IPv4 unicast address family view is displayed.

    • Run ipv4-family vpnv4

      The BGP-VPNv4 address family view is displayed.

    • Run ipv4-family vpn-instance vpn-instance-name

      The BGP-VPN instance IPv4 address family view is displayed.

    • Run ipv4-family multicast

      The BGP-IPv4 multicast address family view is displayed.

    • Run ipv6-family unicast

      The BGP-IPv6 unicast address family view is displayed.

    • Different extended BGP functions must be configured in their respective address family views, while common BGP functions are configured in the BGP view.

    • The Router supports the following MBGP features: basic BGP functions, BGP security (MD5 authentication and keychain authentication), simplifying IBGP network connections (route reflector and confederation), BGP route selection and load balancing, controlling the receiving and advertisement of BGP routes, adjusting the BGP network convergence speed, BGP reliability, BGP route summarization, path MTU auto discovery, and advertising default routs to peers.

    • Some BGP4+ functions can be configured in the BGP view, and some BGP4+ functions need to be configured in the IPv6 unicast address family view. For example, the following BGP4+ functions need to be configured in the IPv6 unicast address family view: load balancing, manual route summarization, route dampening, community, and route reflector.
