HPE Aruba 3810 - Displays the PIM interfaces currently configured

• When the PIM-DM router is actively forwarding a multicast flow out an interface (VLAN.)
• On a PIM-DM originator router (source directly connected) when traffic is entering the router but not forwarding
NOTE: The neighbor field will be empty in this case.
• On a PIM-DM Non-originator router for a short duration after a flow's initial flood/prune cycle is seen. This entry
is cleared after 5 minutes unless the flow is connected within that time period.
[Group Address]
The multicast group IP address for the specific flow (source-group pair.)
[Source Address]
The unicast address of the flow's source.
[neighbor]
The IP address of the upstream multicast router interface (VLAN) from which the multicast flow is coming. A
blank field indicates that the multicast source is directly connected to the router.
[VLAN]
The interface on which the router receives the multicast flow.
Showing the route entry data on the “#2” routing switch
The next figure displays the show ip mroute output on the “ #2” routing switch shown in Figure 9: Multicast
network with a multinetted VLAN on page 60. This case illustrates two multicast groups from the same
multicast source.
