Configuring Route Reflection for BGP VPNv4 Routes

Configuring Route Reflection for BGP VPNv4 Routes

The prerequisite for enabling BGP VPNv4 route reflection is that the RR has established MP-IBGP peer relationships with all client PEs.

Context

For detailed configurations about an RR, see "BGP Configuration" in the NE deviceMid-End RouterConfiguration Guide - IP Routing.

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 | group-name } reflect-client

    The local device is configured as an RR, and its peer is considered as an RR client.

  5. (Optional) Run undo reflect between-clients

    Route reflection between clients through the RR is disabled 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-number

    A reflection policy is configured for the RR. Only IBGP routes whose VPN targets meet the matching rules can be reflected. This allows load balancing among RRs.

  8. Run commit

    The configuration is committed.
