Configuring an MSDP Mesh Group An MSDP mesh group is a group of MSDP speakers that have fully meshed MSDP connectivity among one another. Any SA messages received from a peer in a mesh group are not forwarded to other peers in the same mesh group. Thus, you reduce SA message flooding and simplify peer-RPF flooding. Use the ip msdp mesh-group global configuration command when there are multiple RPs within a domain. It is especially used to send SA messages across a domain. You can configure multiple mesh groups (with different names) in a single device. Follow these steps to create a mesh group:
Procedure Configuring MSDP Configuring an MSDP Mesh Group Command or Action Purpose Step 1 enable Example: Device>enable Enables privileged EXEC mode. • Enter your password if prompted. Step 2 configure terminal Example: Device#configure terminal Enters global configuration mode. Step 3 ip msdp mesh-group name {ip-address | name} Example: Devic(config)#ip msdp mesh-group 2 switch.cisco.com Configures an MSDP mesh group, and specifies the MSDP peer belonging to that mesh group. By default, the MSDP peers do not belong to a mesh group. • For name, enter the name of the mesh group. • For ip-address | name, enter the IP address or name of the MSDP peer to be a member of the mesh group.
Repeat this procedure on each MSDP peer in the group. Step 4 end Example: Device(config)#end Returns to privileged EXEC mode. Step 5 show running-config Example: Verifies your entries. Configuring MSDP 19
