Step 3 Run:
undo pim state-refresh-capable
PIM-DM State-Refresh is disabled.
The interface on which PIM-DM State-Refresh is disabled cannot forward any State-Refresh
message.
NOTE
You can run the pim state-refresh-capable command to re-enable PIM-DM State-Refresh on the interface.

5.7.3 Configuring the Interval for Sending State-Refresh Messages
To prevent pruned interfaces from forwarding messages after the prune state timer times out,
you need to set the interval for sending State-Refresh messages to be shorter than the period for
keeping the Prune state.
Context
Do as follows on all the switchs in the PIM-DM domain:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
pim [ vpn-instance vpn-instance-name ]
The PIM view is displayed.
Step 3 Run:
state-refresh-interval interval
The interval for sending PIM State-Refresh messages is set.
NOTE
l This command is applicable to the first-hop switch connecting with the multicast source.
l The interval for sending PIM State-Refresh messages should be shorter than the timeout period for
keeping the Prune state.
l You can run the holdtime join-prune command to set the timeout period for keeping the Prune state.
----End
5.7.4 Configuring the Period for Receiving the Next State-Refresh
Message
A multicast device may receive PIM State-Refresh messages from multiple routers in a short
period and some PIM State-Refresh messages are repeated. Before the state-refresh timer times
out, the device discards the received repeated State-Refresh messages. The device is allowed to
receive the next State-Refresh message only after the timer times out.
