To configure global settings for PIM6-SM:
1. Click Routing Protocol, PIM6, PIM6-SM.
2. Select Configure Global from the Step list.
3. Set the register rate limit and source of register messages if required.
Also specify any multicast groups which must be routed across the

◆ When this router is configured as a BSR candidate, it starts sending
bootstrap messages to all of its PIM6-SM neighbors. The primary IP
address of the designated VLAN is sent as the candidate’s BSR address.
Each neighbor receiving the bootstrap message compares the BSR
address with the address from previous messages. If the current
address is the same or a higher address, it accepts the bootstrap
message and forwards it. Otherwise, it drops the message.
◆ This router will continue to be the BSR until it receives a bootstrap
message from another candidate with a higher priority (or a higher IP
address if the priorities are the same).
◆ To improve failover recovery, it is advisable to select at least two core
routers in diverse locations, each to serve as both a candidate BSR and
candidate RP. It is also preferable to set up one of these routers as both
the primary BSR and RP.
