Displays information about active multicast sources
sending traffic to groups on the last hop router. The
show ip mroute active [kb/s]
Example:
Device# show ip mroute active
Active IP Multicast Sources - sending >= 4 kbps
Step 9
output of this command provides information about
the multicast packet rate for active sources.
By default, the output of the show ip mroute
command with the active keyword displays
information about active sources sending
traffic to groups at a rate greater than or equal
to 4 kb/s. To display information about active
sources sending low-rate traffic to groups
(that is, traffic less than 4 kb/s), specify a
value of 1 for the kb/s argument. Specifying
a value of 1 for this argument displays
information about active sources sending
traffic to groups at a rate equal to or greater
than 1 kb/s, which effectively displays
information about all possible active source
traffic.

Using PIM-Enabled Routers to Test IP Multicast Reachability
If all the PIM-enabled routers and access servers that you administer are members of a multicast group, pinging
that group causes all routers to respond, which can be a useful administrative and debugging tool.
To use PIM-enabled routers to test IP multicast reachability, perform the following tasks:
Configuring Routers to Respond to Multicast Pings
Follow these steps to configure a router to respond to multicast pings. Perform the task on all the interfaces
of a router and on all the routers participating in the multicast network:
