We have a client on a 3524 switch that needs to join a multicast group. The 3524 is connected to a port on a 6509 port which is a L3 port. The 6509 does have PIM and ip sparse-mode configured on the port that the 3524 is connected to, but the 3524 doesn not do IGMP - it is CGMP only and the client is not able to join the MC group.
Is this a case where configuring the command 'ip cgmp proxy' on the 6509 port connected to the 3524 will help?
If not, how do I get the client on the 3524 to join a MC group through the 6509?
