Configuring A Bsr - HP A5500 SI Switch Series Configuration Manual

To do...
Enable auto-RP
Configuring C-RP timers globally
To enable the BSR to distribute the RP-set information within the BIDIR-PIM domain, C-RPs must
periodically send C-RP-Adv messages to the BSR. The BSR learns the RP-set information from the received
messages, and encapsulates its own IP address together with the RP-set information in its bootstrap
messages. The BSR then floods the bootstrap messages to all PIM routers in the network.
Each C-RP encapsulates a timeout value in its C-RP-Adv messages. Upon receiving a C_RP-Adv message,
the BSR obtains this timeout value and starts a C-RP timeout timer. If the BSR fails to hear a subsequent C-
RP-Adv message from the C-RP within the timeout interval, the BSR assumes the C-RP to have expired or
become unreachable.
The C-RP timers need to be configured on C-RP routers.
Follow these steps to configure C-RP timers globally:
To do...
Enter system view
Enter public network PIM view
or VPN instance PIM view
Configure the C-RP-Adv interval
Configure C-RP timeout time
NOTE:
For more information about the configuration of other timers in BIDIR-PIM, see
common timers."

Configuring a BSR

A BIDIR-PIM domain can have only one BSR, but must have at least one C-BSR. You can configure any
router as a C-BSR. Elected from C-BSRs, the BSR collects and advertises RP information in the BIDIR-PIM
domain.
Configuring a C-BSR
C-BSRs must be configured on routers in the backbone network. When configuring a router as a C-BSR,
be sure to specify a BIDIR-PIM-enabled interface on the router. The following summarizes the BSR
election process:
Initially, every C-BSR assumes itself to be the BSR of the BIDIR-PIM domain, and uses its interface IP
•
address as the BSR address to send bootstrap messages.
When a C-BSR receives the bootstrap message of another C-BSR, it first compares its own priority
•
with the other C-BSR's priority carried in message. The C-BSR with a higher priority wins. If a tie
occurs in the priority, the C-BSR with a higher IP address wins. The loser uses the winner's BSR
