PIM Multicast Routing

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.

The following example configures the router to start sending bootstrap

messages out of the interface for VLAN 1 to all of its PIM-SM neighbors.

Console(config)#ipv6 pim bsr-candidate interface vlan 1 hash 20 priority 200

Console(config)#exit

Console#show ipv6 pim bsr-router

This command configures the rate at which register messages are sent by

the Designated Router (DR) for each (source, group) entry. Use the no

form to restore the default value.

ipv6 pim register-rate-limit rate

no ipv6 pim register-rate-limit

rate - The maximum number of register packets per second.

(Range: 1-65535: Default: 0, which means no limit)

Global Configuration

This command can be used to relieve the load on the Designated Router

(DR) and RP. However, because register messages exceeding the limit are

dropped, some receivers may experience data packet loss within the first

few seconds in which register messages are sent from bursty sources.
