Where are you originating a ping from? A PC or the non-multicast-enabled
router?
A PC should automatically participate in IGMP, and if you have ANY multicast
enabled router on the same LAN with it, then it should participate as an
IGMP querier as well. (show ip igmp interfaces may help here)
A router, however, will not magically serve as an igmp client.

Subject: using multicast from a non multicast speaker
Hello,
I am trying to ping a multicast feed over a dense mode network. I am on a
LAN router that is not enabled for Mcast. There is a multicast router on the
LAN. I cannot get a response. Is this because I am not an IGMP client?
I thought that a non Mcast enable router could ping Mcast feeds, if they are
dirtectly connected to a Mcast router, once you define the correct interface
and make sure of the RPF check?
Sorry...I have a hole in my thinking here.......any someone help.
thanks
Nic
