Appendix B Cisco MWR 2941 Router Command Reference
ip pim bsr-candidate
Usage Guidelines This command causes the router to send bootstrap messages to all its PIM neighbors, with the address
of the designated interface as the BSR address. Each neighbor compares the BSR address with the
address it had from previous bootstrap messages (not necessarily received on the same interface). If the
current address is the same or higher address, it caches the current address and forwards the bootstrap
message. Otherwise, it drops the bootstrap message.
This router continues to be the BSR until it receives a bootstrap message from another candidate BSR
saying that it has a higher priority (or if the same priority, a higher IP address).
Use this command only in backbone routers that have good connectivity to all parts of the PIM domain.
That is, a stub router that relies on an on-demand dialup link to connect to the rest of the PIM domain is
not a good candidate BSR.
You must enable the interface-type with PIM.
When you set the hash-mask-length argument, all groups with the same seed hash correspond to the same
rendezvous point. For example, if this value is 24, only the first 24 bits of the group addresses are
applicable; using this setting allows you to get one rendezvous point for multiple groups.
When you set the priority argument, the BSR with the larger priority is preferred. If the priority values
are the same, the router with the larger IP address is the BSR.
Examples The following example shows how to configure the IP address of the router on Ethernet interface 0/0 to
be a candidate BSR with a priority of 192:
ip pim bsr-candidate ethernet 0/0 192
