Enabling state-refresh capability
Pruned interfaces resume multicast forwarding when the pruned state times out. To prevent this, the
router with the multicast source attached periodically sends an (S, G) state-refresh message, which is
forwarded hop by hop along the initial multicast flooding path of the PIM-DM domain, to refresh the
prune timer state of all the routers on the path. A multi-access subnet can have the state-refresh capability
only if the state-refresh capability is enabled on all PIM routers on the subnet.
Follow these steps to enable the state-refresh capability:
