MSDP debug commands
Multicast Source Discovery Protocol (MSDP) is used by Protocol-Independent Multicast (PIM)
Sparse routers to exchange routing information for PIM Sparse multicast groups across PIM Sparse
domains. Devices running MSDP can discover PIM Sparse sources that are in other PIM Sparse
domains.
The following debug ip msdp commands generate MSDP information.
debug ip msdp
Syntax: [no] debug ip msdp [alarms | events | message]
• alarms - Displays information about the MSDP alarms.
• events - Displays information about the MSDP events.
• message - Displays information about the MSDP messages.
The debug ip msdp command generates information about MSDP alarms, events, and messages.
debug ip msdp alarms
Syntax: [no] debug ip msdp alarms
This command generates information about the MSDP processing alarms.
Brocade# debug ip msdp alarms
: MSDP: S=xxxxxxx P=0 Initiate Transport Connection to MSDP peer
: MSDP: S=xxxxxxx P=0 Initiate Transport Connection to MSDP peer
debug ip msdp events
Syntax: [no] debug ip msdp events
This command tracks originating SA-advertisements, major peer events, and peer-keepalive timer
events.
