(Optional) Configuring Static RPF Peers

(Optional) Configuring Static RPF Peers

Prerequisites

MSDP peers have been configured. For details, see Configuring MSDP Peers.

Context

The device does not perform reverse path forwarding (RPF) checks on SA messages received from static RPF peers. Therefore, Source-Active (SA) messages are not discarded.

If a device has only one remote MSDP peer, the remote MSDP peer automatically becomes the static RPF peer.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run msdp [ vpn-instance vpn-instance-name ]

    The MSDP view is displayed.

  3. Run static-rpf-peer peer-address [ rp-policy ip-prefix-name ]

    The remote MSDP peer is specified as the RPF peer.

    • peer-address: specifies the address of the remote MSDP peer.

    • rp-policy ip-prefix-name: specifies a policy for filtering SA messages based on the source RP address.

      When you specify multiple static RPF peers for a router, pay attention to the following points:

      • If rp-policy is set for all peers, after receiving SA messages from multiple active static RPF peers, the local router filters the SA messages based on the configured rp-policy for each static RPF peer. Only the SA messages that match policy rules are accepted.

      • If no rp-policy is set for the peers, the router accepts all SA messages from the active static RPF peers.
