MSDP Default Peers

You can configure a default peer to accept all SA messages. Configuring a default peer simplifies the peer-RPF checking of SA messages. If no policy is specified, the current peer is the default RPF peer for all SA messages.

When configuring a default peer, you can also specify an optional policy filter. If the peer-RPF check fails, and a policy filter is configured, the default peer rule is applied to see if the SA message should be accepted or rejected.

You can configure multiple default peers with different policies. However, all default peers must either be configured with a default policy or not. A mix of default peers, with a policy and without a policy, is not allowed.

Configure an MSDP (Multicast Source Discovery Protocol) default peer, and optional policy filter using the command:
configure msdp peer [remoteaddr | all] default-peer {default-peer-policy filter-name} {vr vrname}
Remove the default peer using the command:
configure msdp peer [remoteaddr | all] no-default-peer {vr vrname}
Verify that a default peer is configured using the command:
show msdp [peer {detail} | {peer} remoteaddr] {vr vr_name}
