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.

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.
