Configuring BGP GR Helper for MP-BGP

When MP-BGP restarts, the peer relationship is re-established and traffic forwarding is interrupted. If BGP GR Helper is enabled, traffic interruption can be prevented.

Context

Configure BGP GR Helper for MP-BGP on all the PEs (including the PE that serves as the ASBR) and the RRs that reflect the VPNv4 route, unless BGP GR Helper has been configured for MP-BGP when BGP GR Helper is configured between PEs and CEs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run bgp as-number

    The BGP view is displayed.

  3. Run graceful-restart

    BGP GR is enabled.

  4. Run graceful-restart timer wait-for-rib time

    The period during which the restarting speaker and receiving speaker wait for End-Of-RIB messages is set.

    You can adjust parameter values of a BGP GR session as required. Generally, the default values of parameters are recommended.

  5. Run commit

    The configuration is committed.
