PIM Sparse Domain 1 in
example, RP 206.251.21.41 (which is also the originating RP), receives an SA message from the
source, it sends the SA message to its peers within the domain, but the peers do not send the
message back to the originator RP or to each other. The RPs then send the SA message to their
peers in other domains.The process continues until all RPs within the network receive the SA
message. RPs send join and prune messages to appropriate points on the multicast tree towards
the originating RP.

Configuring MSDP mesh group

To configure an MSDP mesh group, enter commands such as the following on each device that will
be included in the mesh group.
BigIron RX(config)# router msdp
BigIron RX(config-msdp-router)# msdp-peer 163.5.34.10 connect-source loopback 2
BigIron RX(config-msdp-router)# msdp-peer 206.251.21.31 connect-source loopback 2
BigIron RX(config-msdp-router)# msdp-peer 206.251.17.31 connect-source loopback 2
BigIron RX(config-msdp-router)# msdp-peer 206.251.13.31 connect-source loopback 2
