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. 

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

Syntax: [no] mesh-group group-name peer-address

The sample configuration above reflects the configuration in Figure 8. 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).

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.

The group-name parameter identifies the mesh group. Enter up to 31 characters for group-name. You can have up to 4 mesh groups within a multicast network. Each mesh group can include up to 15 peers.

The peer-address parameter specifies the IP address of the MSDP peer that is being placed in the mesh group. Each mesh group can include up to 32 peers.

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

A maximum of 32 MSDP peers can be configured per mesh group.

You can use the show ip msdp [ vrf vrf-name ] mesh-group group-name 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. .
