Enabling the LAN prune delay option on the current VLAN
Syntax:
ip pim-dense [lan-prune-delay]
vlan[vid]ip pim-dense [lan-prune-delay]
Enables the LAN prune delay option on the current VLAN. With lan-prune-delay enabled, the routing switch informs downstream neighbors how long it will wait before pruning a flow after receiving a prune request. Other, downstream routers on the same VLAN must send a Join request to override the prune before the lan-prune-delay times out if they want the flow to continue. This prompts any downstream neighbors with hosts continuing to belong to the flow to reply with a Join. If no joins are received after the LAN prune-delay period, the routing switch prunes the flow.
The propagation-delay and override-interval settings determine the lan-prune-delay setting.
Uses the
no form of the
ip pim-dense command to disable the LAN prune delay option.
Default: Enabled
