Enabling or disabling lan prune delay
Syntax:
ip pim-sparse lan-prune-delay
no ip pim-sparse lan-prune-delay
vlan [vid] ip pim-sparse lan-prune-delay
no vlan [vid] ip pim-sparse lan-prune-delayEnables the LAN prune delay option on the current VLAN. With
lan-prune-delay enabled, the router 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 to override the prune before the
lan-prune-delay time if they want the flow to continue. This prompts any downstream neighbors with multicast receivers continuing to belong to the flow to reply with a join. If no joins are received after the
lan-prune-delay period, the router prunes the flow.
The
propagation-delay and
override-interval settings (below) determine the
lan-prune-delay setting.
Uses the
no form of the command to disable the
LAN prune delayoption.
(Default: Enabled)
