Configuring an MBGP Peer

Configuring an MBGP Peer

Valid routing information can be provided for the Reverse Path Forwarding (RPF) check only after a Multicast Border Gateway Protocol (MBGP) connection is enabled in the multicast address family view.

Usage Scenario

The RPF check is performed on multicast packets based on the following routes:
  • Multicast static routes
  • Unicast routes
  • MBGP routes

Valid routing information can be provided for the RPF check only after an MBGP connection is enabled in the multicast address family view.

Pre-configuration Tasks

Before configuring basic MBGP functions, configure basic multicast functions.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run bgp as-number

    The BGP view is displayed.

  3. Run peer ip-address as-number as-number

    The IP address and autonomous system (AS) number of a remote peer are specified.

  4. (Optional) Run peer { ipv4-address | group-name } connect-interface { interface-type interface-number | ipv4-source-address }

    The local interface and the source address used to set up a BGP connection are specified.

    If the BGP connection is set up through a Loopback interface or a sub-interface, this command must be configured.

  5. (Optional) Run peer { ip-address | group-name } ebgp-max-hop [ hop-count ]

    The maximum number of hops of an External Border Gateway Protocol (EBGP) connection is set.

    The command is valid only for EBGP peers.

    If the EBGP connection is set up through a Loopback interface, this command must be configured.

  6. Run ipv4-family multicast

    The BGP-IPv4 multicast address family view is displayed.

  7. Run peer { peer-address | group-name } enable

    MBGP is enabled for a BGP peer or peer group, which then becomes an MBGP peer or peer group.

    • group-name: specifies the name of a BGP peer group.

    • peer-address: specifies the IP address of a remote BGP peer.

  8. Run commit

    The configuration is committed.

Checking the Configurations

After the configuration is complete, you can check whether the configuration has taken effect.

Run the display bgp multicast peer [ peer-address ] [ verbose ] command to check information about a specified or all MBGP peers.
