Chapter25 Configuring MSDP Configuring MSDP
Beginning in privileged EXEC mode, follow these steps to shut down a peer:
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 multilayer switch that borders a PIM sparse-mode region with a
dense-mode region. By default, active sources in the den se- mo de re gion d o n ot par tic ipa te in M SD P.
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 configur e the bo rder ro uter to se nd SA
messages for sources active in the dense-mode region to the MSDP peers:
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 ip msdp shutdown {peer-name | peer
address}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.
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.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 ip msdp border sa-address type number 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 type number, specify the interface type and number 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.
Step3 ip msdp redistribute [list
access-list-name] [asn
aspath-access-list-number] [route-map
map]
Configure which (S,G) entries from the multicast routing table are
advertised in SA messages.

page25-9.
Step4 end Return to privileged EXEC mode.
