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 amount of 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 IPv6 PIM-DM state, and resets the waiting timer.
The hop limit 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
hop limit comes down to 0. A state refresh message with a large hop limit value might cycle on a
small network. To control the propagation scope of state refresh messages, configure an appropriate
hop limit value based on the network size on the router directly connected with the IPv6 multicast
source.
