This command configures the override interval, or the time it takes a
ipv6 pim
downstream router to respond to a lan-prune-delay message. Use the no
override-interval
form to restore the default setting.

The override interval configured by this command and the propagation

When other downstream routers on the same VLAN are notified that
this upstream router has received a prune request, they must send a
Join to override the prune before the prune delay expires if they want
to continue receiving the flow. The message generated by this
command effectively prompts any downstream neighbors with hosts
receiving the flow to reply with a Join message. If no join messages are
received after the prune delay expires, this router will prune the flow.
Prune delay is the sum of the effective propagation-delay and effective
override-interval, where effective propagation-delay is the largest
propagation-delay from those advertised by each neighbor (including
this switch), and effective override-interval is the largest override-
interval from those advertised by each neighbor (including this switch).
