Configuring Multicast Source Discovery Protocol (MSDP)

• Configure the MSDP peers
NOTE
The PIM Sparse Rendezvous Point (RP) is also an MSDP peer.
Routers that run MSDP must also run BGP. Also, the source address used by the MSDP router must
be the same source address used by BGP.
Enabling MSDP
NOTE
You must save the configuration and reload the software to place the change into effect.
To enable MSDP, enter the following commands.
BigIron RX(config)# router msdp
BigIron RX(config-msdp-router)# write memory
Syntax: [no] router msdp
Configuring MSDP peers
To configure an MSDP peer, enter a command such as the following at the MSDP configuration
level.
BigIron RX(config-msdp-router)# msdp-peer 205.216.162.1
Syntax: [no] msdp-peer <ip-addr> [connect-source loopback <num>]
The <ip-addr> parameter specifies the IP address of the neighbor.
The connect-source loopback <num> parameter specifies the loopback interface you want to use
as the source for sessions with the neighbor.
NOTE
It is strongly recommended that you use the connect-source loopback <num> parameter when
issuing the msdp-peer command. If you do not use this parameter, the BigIron RX uses the subnet
interface configured on the port. Also, make sure the IP address of the connect-source loopback is
the same as the source IP address used by the MSDP router, the PIM-RP, and the BGP router.
The commands in the following example add an MSDP neighbor and specify a loopback interface
as the source interface for sessions with the neighbor. By default, the BigIron RX uses the subnet
address configured on the physical interface where you configure the neighbor as the source
address for sessions with the neighbor.
BigIron RX(config)# interface loopback 1
BigIron RX(config-lbif-1)# ip address 9.9.9.9/32
BigIron RX(config-lbif-1)# exit
BigIron RX(config)# router msdp
BigIron RX(config-msdp-router)# msdp-peer 2.2.2.99 connect-source loopback 1
