Monitoring and Maintaining MSDP

Monitoring and Maintaining MSDP

To monitor MSDP SA messages, peers, state, or peer status, use the following commands in EXEC mode as needed:

Command	Purpose
Router# debug ip msdp [peer-address peer-name]	Debugs an MSDP activity.
[detail] [routes]
Router# debug ip msdp resets	Debugs MSDP peer reset reasons.
Router# show ip msdp count [as-number]	Displays the number of sources and groups originated in SA
	messages from each autonomous system. The ip msdp
	cache-sa-stateglobal configuration command must be
	configured for this command to produce any output.
Router# show ip msdp peer [peer-address	Displays detailed information about an MSDP peer.
peer-name]
Router# show ip msdp sa-cache [group-address	Displays (S, G) state learned from MSDP peers.
source-address group-name source-name]
[as-number]
Router# show ip msdp summary	Displays MSDP peer status and SA message counts.

To clear MSDP connections, statistics, or SA cache entries, use the following commands in EXEC modeas needed:

Command	Purpose
Router# clear ip msdp peer [peer-address	Clears the TCP connection to the specified MSDP peer,
peer-name]	resetting all MSDP message counters.
Router# clear ip msdp statistics [peer-address	Clears the TCP connection to the specified MSDP peer,
peer-name]	resetting all MSDP message counters.
Router# clear ip msdp sa-cache [group-address	Clears the SA cache entries for all entries, all sources for a
peer-name]	specific group, or all entries for a specific source/group pair.

To enable Simple Network Management Protocol (SNMP) monitoring of MSDP, use the following commands in global configuration mode:

	Command	Purpose
Step 1
	Router# snmp-server enable traps msdp	Enables the sending of MSDP notifications for use with SNMP.
		The snmp-server enable traps command enables both traps
		and informs.
Step 2
	Router# snmp-server host host [traps	Specifies the recipient (host) for MSDP traps or informs.
	informs] [version {1 2c 3 [auth priv
	noauth ]}] community-string [udp-port
	port-number]msdp
