Displaying PIM route data
Syntax:
show ip [mroute]
Without parameters, lists multicast route entries in the following situations:
• 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.)
