By default, no domain border is set. After this configuration is performed, a bootstrap
message cannot cross the border but other PIM packets can. This configuration can
effectively divide a network into domains using different BSRs.

7.2.6 Configure Candidate-BSRs

In a PIM domain, one or more candidate BSRs should be configured. A BSR (Bootstrap
Router) is elected among candidate BSRs. The BSR takes charge of collecting and
advertising RP information.
The automatic election among candidate BSRs is described as follows:
One interface which has started PIM-SM must be specified when configuring the router
as the candidate BSR.
At first, each candidate BSR considers itself as the BSR of the PIM-SM domain, and
sends Bootstrap message by taking the IP address of the interface as the BSR
address.
When receiving Bootstrap messages from other routers, the candidate BSR will
compare the BSR address of the newly received Bootstrap message with that of itself.
Comparison standards include priority and IP address. The bigger IP address is
considered better when the priority is the same. If the new BSR address is better, the
candidate BSR will replace its BSR address and stop regarding itself as the BSR.
Otherwise, the candidate BSR will keep its BSR address and continue to regard itself
as the BSR.
Perform the following configuration in PIM view.
