DGS-6604 ip pim state-refresh origination-interval ip pim state-refresh origination-interval 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. ip pim state-refresh origination-interval SECONDS Syntax Description SECONDS The number of seconds that can be configured for the interval between staterefresh messages. The range is 4 to 100. Default Command Mode Usage Guideline Example 60 seconds Interface configuration 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. The following example sets the State Refresh Origination Interval to 100 seconds. Switch(config)# interface vlan1 Switch(config-if)# ip pim state-refresh origination-interval 100 Verify the settings by entering the show ip pim interface command. CLI Reference Guide 300
