ip multicast-msdp
2 Peer PIM systems in different administrative domains.
CONFIGURATION mode
ip msdp peer connect-source
Examples of Configuring and Viewing MSDP
R3(conf)#ip multicast-msdp
R3(conf)#ip msdp peer 192.168.0.1 connect-source Loopback 0
R3(conf)#do show ip msdp summary
Peer Addr Local Addr State Source SA Up/Down
Description
To view details about a peer, use the show ip msdp peer command in EXEC privilege mode.
Multicast sources in remote domains are stored on the RP in the source-active cache (SA cache). The system
does not create entries in the multicast routing table until there is a local receiver for the corresponding
multicast group.

Manage the Source-Active Cache
Each SA-originating RP caches the sources inside its domain (domain-local), and the sources which it has
learned from its peers (domain-remote).
By caching sources:
• domain-local receivers experience a lower join latency
• RPs can transmit SA messages periodically to prevent SA storms
• only sources that are in the cache are advertised in the SA to prevent transmitting multiple copies of the
same source information
Viewing the Source-Active Cache
To view the source-active cache, use the following command.
• View the SA cache.
