Configuring MSDP
Beginning in privileged EXEC mode, follow these steps to shut down a peer. This procedure is optional.
Command
Step 1
configure terminal
Step 2
ip msdp shutdown {peer-name | peer
address}
Step 3
end
Step 4
show running-config
Step 5
copy running-config startup-config
To bring the peer back up, use the no ip msdp shutdown {peer-name | peer address} global
configuration command. The TCP connection is reestablished
Including a Bordering PIM Dense-Mode Region in MSDP
You can configure MSDP on a switch that borders a PIM sparse-mode region with a dense-mode region.
By default, active sources in the dense-mode region do not participate in MSDP.
Note
We do not recommend using the ip msdp border sa-address global configuration command. It is better
to configure the border router in the sparse-mode domain to proxy-register sources in the dense-mode
domain to the RP of the sparse-mode domain and have the sparse-mode domain use standard MSDP
procedures to advertise these sources.
Beginning in privileged EXEC mode, follow these steps to configure the border router to send SA
messages for sources active in the dense-mode region to the MSDP peers. This procedure is optional.
Command
Step 1
configure terminal
Step 2
ip msdp border sa-address interface-id
Step 3
ip msdp redistribute [list
access-list-name] [asn
aspath-access-list-number] [route-map
map]
Step 4
end

Purpose
Enter global configuration mode.
Administratively shut down the specified MSDP peer without losing
configuration information.
For peer-name | peer address, enter the IP address or name of the MSDP
peer to shut down.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Configure the switch on the border between a dense-mode and
sparse-mode region to send SA messages about active sources in the
dense-mode region.
For interface-id, specify the interface from which the IP address is
derived and used as the RP address in SA messages.
The IP address of the interface is used as the Originator-ID, which is the
RP field in the SA message.
Configure which (S,G) entries from the multicast routing table are
advertised in SA messages.

page
35-9.
Return to privileged EXEC mode.
