Configuring MSDP Chapter 33 Configuring MSDP 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 switch. Beginning in privileged EXEC mode, follow these steps to create a mesh group. This procedure is optional. Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Command configure terminal ip msdp mesh-group name {ip-address | name} end show running-config copy running-config startup-config Purpose Enter global configuration mode. Configure an MSDP mesh group, and specify 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. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. Repeat this procedure on each MSDP peer in the group. To remove an MSDP peer from a mesh group, use the no ip msdp mesh-group name {ip-address | name} global configuration command. Shutting Down an MSDP Peer If you want to configure many MSDP commands for the same peer and you do not want the peer to become active, you can shut down the peer, configure it, and later bring it up. When a peer is shut down, the TCP connection is terminated and is not restarted. You can also shut down an MSDP session without losing configuration information for the peer. 33-16 Catalyst 3560 Switch Software Configuration Guide 78-16156-01
