DGS-6604 ip pim join-prune-interval ip pim join-prune-interval Use this command to configure a Join/Prune interval value different from the default (60 seconds). ip pim join-prune-interval SECONDS Syntax Description SECONDS The number of seconds that can be configured for the interval between Join/ Prune messages. The range is 1 to 18000. Default Command Mode Usage Guideline Example 60 seconds VLAN interface configuration This command is only valid for the VLAN interface. This command is valid for SM only. When configuring the Join/Prune interval, the user needs to consider the factors, such as configured bandwidth and expected average number of multicast route entries for the attached network or link (for example, the period would be longer for lower-speed links, or for routers in the center of the network that expect to have a larger number of entries). For SM-mode, the router will periodically send the join message based on this interval. The hold-time in a Join/Prune message is 3.5 * join-prune-interval. The receiving router will start a timer based on this hold-time, and prune the interface if no join message is received on this interface. The following example changes the PIM Join/Prune timer to 120 seconds. Switch(config)# interface vlan1 Switch(config-if)# ip pim join-prune-interval 120 Verify the settings by entering the show ip pim interface command. CLI Reference Guide 292
