protocols msdp peer <peer-address> default-peer prefix-list <prefix-list-name>
Configures a default peer filter for a MSDP peer from which to accept all SA messages that are received from a specific RP address.
- peer-address
- The IPv4 address of an MSDP peer.
- prefix-list-name
- The name of a previously defined prefix list. This list is the per-peer RP-address filter that specifies RP addresses for which the MSDP speaker accepts (that is, caches). The RP address is gained from the RP Address field of an MSDP SA packet.
Configuration mode
protocols {
msdp {
peer peer-address {
default-peer {
prefix-list prefix-list-name
}
}
}
}Choose a name for the prefix list that reflects the default peer. Configuring multiple default peers with the same prefix list name enables you to use all the default peers simultaneously for multiple RP prefixes. Configuring multiple default peers without specifying a prefix list name means that all SA messages are accepted by active peers. If a default peer fails, the next configured default peer accepts the SA messages.
Use the set form of this command to define a default peer from which to accept all SA messages. The RPF check is not applied to the SA messages that are received from the default peer.
Use the delete form of this command to delete a default peer from which to accept all SA messages.
Use the show form of this command to display the default peers from which to accept all SA messages.
