You need to make sure you turn on CGMP on the router also. By default when
you turn on pim-dm on an interface that will do IGMP. You need to make sure
you enter "ip cgmp" on the interface that the switch is on in addition to
"set cgmp enable" on the Cat.

Not sure I understand fully what you mean, but the Catalyst uses CGMP to see
which devices need multicast traffic.

Subject: Trying simple LAB multicasting
I just begin in multicasting...
1) The lab say configure multicast R1,R2....
No problem ip multicast-routing
and on the interface ip pim dense-mode
2) Rx should explicity join the group 229.2.2.2
no problem ip igmp join-group 229.2.2.2
3)Configure the catalyst to be able to see R1 and R2 are multicast router
but no R3
and configure catalyst to send traffic to 229.2.2.2
Some useful link or explain will be welcome...
