Configuring Route Reflection for the Routes of the BGP VPN Instance

Configuring Route Reflection for the Routes of the BGP VPN Instance

Context

Perform the following steps on the RR.

Procedure

  1. Run system-view

    The system view is displayed.

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

    The BGP view is displayed.

  3. Run ipv4-family vpn-instance vpn-instance-name

    The BGP VPN instance IPv4 address family view is displayed.

  4. Enable route reflection for the routes of the BGP VPN instance on the RR.

    • Run the peer group-name reflect-client command to enable route reflection if the RR establishes the IBGP connection with the peer group consisting of all client CEs.

    • Run the peer ipv4-address reflect-client command to enable route reflection if the RR establishes the IBGP connection with each PE rather than the peer group. Run this command for each PE.

  5. (Optional) Run undo reflect between-clients

    Route reflection is disabled between clients.

    If the clients of an RR have established full-mesh connections with each other, the undo reflect between-clients command can be used to disable route reflection between clients. This reduces the link cost. By default, route reflection is enabled between the clients of an RR.

  6. (Optional) Run reflector cluster-id cluster-id

    The RR cluster ID is set.

    If a cluster has multiple RRs, set the same cluster ID for these RRs to prevent routing loops. By default, the cluster ID is the router ID.

  7. Run commit

    The configuration is committed.
