DownStream Interfaces:
– VLAN: Lists the VID of the destination VLAN on the next-
hop multicast router.
– Prune Reason: Identifies the reason for pruning the flow to the
indicated VLAN:
• Prune: A neighbor multicast router has sent a prune
request.
• Assert: Another multicast router connected to the
same VLAN has been elected to provide the path for
the specified multicast group traffic.
• Other: Used where the VLAN is in the pruned state
for any reason other than the above two reasons
(such as no neighbors exist and no directly con-
nected hosts have done joins).
