MSDP Configuration

Step Task Command
1 Enable MSDP by configuring an MSDP peer to the local router.

To delete an MSDP peer, use the no form of this command.

ip msdp peer peer-address connect-source type-number [remote-as as-number]
2 Configure an Originator ID for the router that originates SA messages. This configures the RP address in SA messages to be the address of the originating router‘s interface.

To remove the Originator ID, use the no form of this command.

ip msdp originator-id interface-id
3 Configure MSDP filters that enable MSDP to control how multicast sources and groups are learned and advertised.

Configure an incoming filter list (sa-filter in) for Source-Active messages received from a specified MSDP peer.

Configure an outgoing filter list (sa-filter out) for Source-Active messages sent to a specified MSDP peer.

To remove a filter, use the no form of this command.

ip msdp sa-filter in peer-address [list access-list-name]

ip msdp sa-filter out peer-address [list access-list-name]

4 (Optional) Configure a BSR border router to limit BSR messages in a PIM domain. BSR messages from other PIM domains can cause a wrong RP selection for this domain. This command prevents this border router from receiving BSR messages outside the PIM domain and sending BSR messages out.

To remove the border router, use the no form of this command.

ip pim bsr-border
5 Configure an MSDP mesh group by running this command for each MSDP peer in the group.

To remove an MSDP peer from the mesh group, use the no form of this command.

ip msdp mesh-group group-name peer-address
6 Administratively shut down an MSDP peer. When a peer is shut down, the TCP connection is terminated and not restarted. ip msdp shutdown peer-address
7 Clear the MSDP TCP connection to the specified MSDP peer and reset all MSDP message counters. clear ip msdp peer [peer-address]
8 Clear the SA cache of all entries. clear ip msdp sa-cache
9 Clear statistics counters for one or all of the MSDP peers. clear ip msdp statistics [peer-address]
