DGS-6604 ip pim state-refresh origination-intervalCLI Reference Guide 300ip pim state-refresh origination-intervalConfigure a PIM-DM State-Refresh origination interval different from the defaultvalue (60 seconds). The origination interval is the number of seconds betweenPIM-DM State Refresh control messages.ip pim state-refresh origination-interval SECONDSDefault 60 secondsCommand Mode Interface configurationUsage Guideline This command is valid for the DM mode.Configure this command on the first hop, PIM dense mode routers that aredirectly connected to sources for PIM-DM multicast groups.The purpose of this message is to reduce overhead spent on the cycle in floodingand pruning of traffic. For each state-refresh origination interval, the first-hoprouter will initiate this message and send it to the down-stream hops. Thus, thedown-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 thecorresponding interfaces.Example The following example sets the State Refresh Origination Interval to 100seconds.Verify the settings by entering the show ip pim interface command.Syntax DescriptionSECONDS The number of seconds that can be configured for the interval between state-refresh messages. The range is 4 to 100.Switch(config)# interface vlan1Switch(config-if)# ip pim state-refresh origination-interval 100
