How do I forward IGMP Joins without enabling PIM??

I am connecting a Cisco Router to another proprietary device which can issue and respond to IGMP queries but is not capable of running PIM.  I would like to be able to forward any IGMP joins from other router ports to this device so that I can send Multicast traffic.  I toyed over the use of Multicast static routes and IGMP joins on interfaces but as we are going to be using a lot of Multicast groups, I don't want an unwieldy configuration.  There must be a way of doing this without using PIM.

Thanks

Eric,

In order for the device to issue and respond to IGMP queries, then pim must be enable. this is a pre-requisit. I am wondering how the other router could issue IGMP queries and listen to IGMP membership from hosts without pim enabled on the interface.

If you want to work IGMP ,you need to configure IGMP snooping on router . or PIM.

I would expected that this would do it:
> (config-if)# ip igmp snooping querier

if you dont configure either of above two IGMP  Joins wont work.

Hope this helps!!

Thanks & Regards,
