Configuring MSDP Mesh Group Example

To configure an MSDP mesh group, you must define MSDP peers and then add the MSDP pers into a mesh group. The configuration must be added on each device in the mesh group.

You first configure the MSDP peers using the msdp-peer command to assign their IP addresses and the loopback interfaces.

Next, place the MSDP peers within a domain into a mesh group. Use the mesh-group command. There are no default mesh groups. You can have up to 4 mesh groups within a multicast network. A maximum of 32 MSDP peers can be configured per mesh group.

Note: On each device that will be part of the mesh group, there must be a mesh group definition for all the peers in the mesh group.

The following sample configuration reflects the configuration in Example of MSDP Mesh Group. On RP 206.251.21.31, you specify its peers within the same domain (206.251.18.31, 206.251.19.31, and 206.251.20.31). 

device(config)# router msdp
device(config-msdp-router)# msdp-peer 206.251.18.31 connect-source loopback 2
device(config-msdp-router)# msdp-peer 206.251.19.31 connect-source loopback 2
device(config-msdp-router)# msdp-peer 206.251.20.31 connect-source loopback 2
device(config-msdp-router)# mesh-group GroupA 206.251.18.31
device(config-msdp-router)# mesh-group GroupA 206.251.19.31
device(config-msdp-router)# mesh-group GroupA 206.251.20.31
device(config-msdp-router)# exit

You can use the show ip msdp mesh-group command to view the details of a specific mesh group or the mesh group details for the VRF instance specified by the vrf-name variable.
