9.3.1.5 PIM Debug
To activate PIM-SM debugging, use the following command.
Command Mode Description
debug pim {all | events | nexthop
| mib | mfc | nsm | packet [in |
out ] | state | timer}
Activates PIM debugging.
all : all PIM debugging
events: PIM events
nexthop: PIM-SM nexthop communications
mib: PIM-SM MIBs
mfc: MFC add/delete/update
nsm: PIM-SM network service module communications
packet: incoming and/or outgoing packets
state: state transition on all PIM-SM FSMs
debug pim timer assert [at] Enables the PIM-SM assert timers debugging.
debug pim timer bsr [bst | crp] Enables the PIM-SM BSR timer’s debugging.

debug pim timer register [rst]
Enable
Enables the PIM-SM register timer’s debugging.
9.3.2 BSR and RP
There are two ways to decide RP as central of PIM-SM on multicast network. One is that
network administrator manually decides RP and the other way is that RP is automatically
decided by exchanging information between multicast routers installed on network. The
information transmitted between multicast routers in the automatic way is called Bootstrap
message and the router, which sends this Bootstrap message, is called BSR (Bootstrap
Router). All PIM routers existing on multicast network can be BSR.
Routers that want to be BSP are named as candidate-BSR and one router, which has the
highest priority, becomes BSR among them. If there are routers, which have same priority,
then one router, which has the highest IP address, becomes BSR. Bootstrap message in-
cludes priority to decide BSR, hash-mark to be used in Hash, and RP information. After
deciding BSR, routers, which support RP, transmit candidate-RP message to BSR. Can-
didate-RP message includes priority, IP address, and multicast group. Then BSR adds
candidate-RP message to Bootstrap message and transmits it to another PIM router.
Through this transmitted Bootstrap message, RP of multicast group is decided.
User’s equipment belonged in PIM-SM network can be candidate-BSR and BSR is de-
cided among them. Candidate-BSR transmits Bootstrap message to decide BSR. You
can configure priority to decide BSR among Bootstrap messages and Hash-mask.
9.3.3 Bootstrap Router (BSR)
The information transmitted between multicast routers in the automatic way is called
Bootstrap message and the router, which sends this Bootstrap message, is called BSR
(Bootstrap Router). All PIM routers existing on multicast network can be BSR. Routers,
which want to be BSP, are named candidate-BSR and one router, which has the highest
