The system view is displayed.
Step 2 Run:
pim [ vpn-instance vpn-instance-name ]
The PIM view is displayed.
Step 3 Run:
c-bsr hash-length hash-length
The hash mask length of a C-BSR is set.
Step 4 Run:
c-bsr priority priority
The priority of the C-BSR is set.
Step 5 Run:
c-bsr interval interval
The interval for the BSR to send Bootstrap messages is set.
Step 6 Run:
c-bsr holdtime interval
The time of holding the Bootstrap message received from a BSR is set.
The BSR periodically sends a Bootstrap message to the network. After receiving the Bootstrap
message, the switchs keep the message for a certain time. During the period, the BSR election
stops temporarily. If the Holdtime timer times out, a new round of BSR election is triggered
among C-BSRs.
NOTE
Ensure that the value of c-bsr holdtime is greater than the value of c-bsr interval. Otherwise, the winner
of BSR election cannot be fixed.

boundary. Multiple BSR boundary interfaces divide the network into different PIM-SM
domains.
