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.

This example sets the register rate limit to 500 pps.

This command configures the IP source address of a register message to
an address other than the outgoing interface address of the designated
router (DR) that leads back toward the rendezvous point (RP). Use the
no
form to restore the default setting.

When the source address of a register message is filtered by intermediate
network devices, or is not a uniquely routed address to which the RP can
send packets, the replies sent from the RP to the source address will fail to
reach the DR, resulting in PIM-SM protocol failures. This command can be
used to overcome this type of problem by manually configuring the source
address of register messages to an interface that leads back to the RP.

This example sets the register rate limit to 500 pps.
