Configuring BGP IPv4 VPN Route Reflection on an ASBR

Route reflection on an ASBR is used to reflect the VPNv4 routes advertised by the PE in the same AS to other PEs. As a result, PEs do not need to set up BGP peer relationships, which simplifies configurations.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run bgp as-number

    The BGP view is displayed.

  3. Run ipv4-family vpnv4

    The BGP-VPNv4 address family view is displayed.

  4. Run peer peer-ipv4-address reflect-client

    The ASBR is configured as an RR, and the PE is configured as a client. If you need to configure multiple PEs as clients, repeatedly run this command.

  5. (Optional) Run undo reflect between-clients

    Route reflection between clients through the RR is disabled. You need to run this command if the clients are fully connected.

  6. Run undo policy vpn-target

    The function to filter VPNv4 routes based on VPN targets is disabled.

  7. (Optional) Run rr-filter extcomm-filter-name

    A reflection policy is configured for the RR.

  8. Run commit

    The configuration is committed.
