Configuring state refresh parameters
The state refresh interval determines the interval at which a router sends state refresh messages. It
is configurable.
A router might receive duplicate state refresh messages within a short time. To prevent this situation,
you can configure the time that the router must wait to accept a new state refresh message. If the
router receives a new state refresh message before the timer expires, it discards the message. If the
router receives a new state refresh message after the timer expires, it accepts the message,
refreshes its own PIM-DM state, and resets the waiting timer.
The TTL value of a state refresh message decrements by 1 whenever it passes a router before it is
forwarded to the downstream node. The state refresh message stops being forwarded when the TTL
value comes down to 0. A state refresh message with a large TTL value might cycle on a small
network. To effectively control the propagation scope of state refresh messages, configure an
appropriate TTL value based on the network size on the router directly connected with the multicast
source.
