Monitoring MSDP
SUMMARY STEPS
1. enable
2. debug ip msdp [peer-address | peer-name] [detail] [routes]
3. debug ip msdp resets
4. show ip msdp count [as-number]
5. show ip msdp peer [peer-address | peer-name]
6. show ip msdp sa-cache [group-address | source-address | group-name | source-name] [as-number]
7. show ip msdp summary
DETAILED STEPS
Step 1 enable
Example:
Device# enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
debug ip msdp [peer-address | peer-name] [detail] [routes]
Use this command to debug MSDP activity.
Use the optional peer-address or peer-name argument to specify for which peer debug events are logged.
The following is sample output from the debug ip msdp command:
Example:
Device# debug ip msdp
MSDP debugging is on
Device#
