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 multilayer switch.
Beginning in privileged EXEC mode, follow these steps to create a mesh group:
Command
Step 1
configure terminal
Step 2
ip msdp mesh-group name {ip-address |
name}
Step 3
end
Step 4
show running-config
Step 5
copy running-config startup-config
Step 6
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.

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.
