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.

can configure priority to decide BSR among Bootstrap messages and Hash-mask.

Bootstrap Router (BSR)

(Bootstrap Router). All PIM routers existing on multicast network can be BSR. Routers,
