Configure a PIM-DM State-Refresh origination interval different from the default
value (60 seconds). The origination interval is the number of seconds between
PIM-DM State Refresh control messages.

Usage Guideline
This command is valid for the DM mode.
Configure this command on the first hop, PIM dense mode routers that are
directly connected to sources for PIM-DM multicast groups.
The purpose of this message is to reduce overhead spent on the cycle in flooding
and pruning of traffic. For each state-refresh origination interval, the first-hop
router will initiate this message and send it to the down-stream hops. Thus, the
down-stream routers can do an action similar to prune. On receiving this prune,
the upstream will refresh the Prune timer, and thus not flood the traffic to the
corresponding interfaces.
Example
The following example sets the State Refresh Origination Interval to 100
seconds.
Verify the settings by entering the
show ip pim
interface command.
Syntax Description
