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 ipv6-family vpnv6

    The BGP IPv6 VPN address family view is displayed.

  4. Enable the route reflection for BGP IPv6 VPN routes on the RR.

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

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

  5. Run undo policy vpn-target

    The filtering of IPv6 VPN routes based on the VPN target is disabled.

  6. (Optional) Run rr-filter extcomm-filter-number

    The reflection policy is configured for the RR.

    To allow an RR to filter routes to be reflected, run the rr-filter command. Only IBGP routes of which the route-target extended community attribute matches the reflection policy can be reflected.

  7. Run commit

    The configuration is committed.
