Displaying PIM-SM Data and Configuration Settings
Unicast Routing Protocol: Identifies the IP routing protocol
through which the router learned the upstream interface for
the current multicast flow. The listed protocol will be either
RIP, OSPF, or Static Route.
Downstream Interfaces:
VLAN: Lists the VID of the VLAN the router is using to send the
outbound packets of the current multicast flow to the next-hop
router.
State: Indicates whether the outbound VLAN and next-hop
router for the current multicast flow are receiving datagrams.
– Pruned: The router has not detected any joins from the
current multicast flow and is not currently forwarding
datagrams in the current VLAN.
– Forwarding: The router has received a join for the current
multicast flow and is forwarding
datagrams in the current VLAN.
Up Time (Sec): Indicates the elapsed time in seconds since the
router learned the displayed information about the current
multicast flow.
