(Optional) Configuring Static RPF 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
- Run system-view
The system view is displayed.
- Run msdp [ vpn-instance vpn-instance-name ]
The MSDP view is displayed.
- 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.
