Command context





Administrators or local user group members with execution rights for this command.


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 interface must send a join to override the prune before the LAN-prune-delay time to continue the flow. 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 determine the LAN-prune-delay setting.


Enabling and disabling the LAN prune delay:

switch(config)# interface vlan40
switch(config-if-vlan)# ip pim-dense lan-prune-delay
switch(config-if-vlan)# no ip pim-dense lan-prune-delay
