The connect-source loopbacknum parameter specifies the loopback interface you want to use as
the source for sessions with the neighbor and must be reachable within the VRF.

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 device uses the IP address of the
outgoing interface. You should also make sure the IP address of the connect-source loopback is the
source IP address used by the PIM-RP, and the BGP device.

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 device uses the subnet address
configured on the physical interface where you configure the neighbor as the source address for
sessions with the neighbor.

device(config)# interface loopback 1

device(config-lbif-1)# ip address 9.9.9.9/32

device(config)# router msdp

device(config-msdp-router)# msdp-peer 2.2.2.99 connect-source loopback 1

Disabling an MSDP peer

To disable an MSDP peer, enter the following command at the configure MSDP router level.

device(config-msdp-router)# msdp-peer 205.216.162.1 shutdown

 

To disable the MSDP VRF peer named "blue", enter the following commands.

device(config)# router msdp vrf blue

device(config-msdp-router-vrf-blue)# no msdp-peer 205.216.162.1 

Syntax: [no] msdp-peer ip-addr shutdown

The ip-addr parameter specifies the IP address of the MSDP peer that you want to disable.

Designating the interface IP address as the RP IP address

When an RP receives a Source Active message, it checks its PIM Sparse multicast group table for
receivers for the group. If a receiver exists the RP sends a Join to the source.

By default, the IP address included in the RP address field of the SA message is the IP address of the
originating RP. An SA message can use the IP address of any interface on the originating RP. (The
interface is usually a loopback interface.)

To designate an interface IP address to be the IP address of the RP, enter commands such as the
following.

device(config)# 

interface loopback 2

device(config-lbif-2)# ip address 2.2.1.99/32

device(config)# router msdp

device(config-msdp-router)# originator-id loopback 2

device(config-msdp-router)# exit

To specify VRF information, enter the following commands at the MSDP VRF configuration level.

device(config)# 

interface loopback 2

device(config-lbif-2)# ip address 2.2.1.99/32
