PIM Multicast Routing
– 1588 –
◆ 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.
E XAMPLE
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

Console#
ipv6 pim register-
rate-limit
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)

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.
