I have configured multicast in our enterprise using Anycast RP, two RPs and ip pim sparse-mode on all interfaces. When I look at the mroute table I notice a lot of multicast group addresses that I am not familiar with. Here is a short list of what shows up:
(*, 232.133.104.73), 33w2d/00:03:03, RP 164.72.239.42, flags: S
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
Port-channel3, Forward/Sparse, 14w6d/00:03:03
(*, 235.80.68.83), 37w4d/00:02:58, RP 164.72.239.42, flags: SJC
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
FastEthernet4/5, Forward/Sparse, 3d03h/00:02:23
Port-channel3, Forward/Sparse, 14w6d/00:02:42
(*, 226.195.91.116), 03:07:11/00:03:22, RP 164.72.239.42, flags: S

Outgoing interface list:

Outgoing interface list:

Outgoing interface list:
Port-channel3, Forward/Sparse, 1w4d/00:03:14
This output is from a 6509/sup720 with eigrp and multicast routing turned on. It is also one of the RPs.
I want to find out what/where/who is on the network with multicast applications and document all the mulitcast groups so I know what is going on.
How do I use the router multicast commands, sho pim, sho mroute, etc., to locate where the devices are that are putting these entries in the mroute table?
