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 si mp lify 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.
To remove an MSDP peer from a mesh group, use the no ip msdp mesh-group name
{ip-address|name} glo ba l c onfigurati on c om mand.
Shutting Down an MSDP Peer
If you want to configure many MSDP commands for the same peer an d y ou do no t want the p eer to
become active, you can shut down the peer , co nf igu re it, and later brin g it up . When a peer is shut d o wn ,
the TCP connection is terminated and is not restarted. You can also shut down an MSDP session withou t
losing configuration information for the peer.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 ip msdp mesh-group name {ip-address |
name}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.
Step3 end Return to privileged EXEC mode.
Step4 show running-config Verify your entries.
Step5 copy running-config startup-config (Optional) Save your entries in the configuration file.
Step6 Repeat this procedure on each MSDP peer in the group.
