Multicast query


I have two routers interfaces on a LAN. A PIM election is made, the DR is the router with the highest IP. It is said that it's this router that send IGMP query. Another election (IGMP) is made, the query router is the one with the lowest IP address. So which router should send IGMP query? My first tests show me that the query router send IGMP query.

But in that case it isn't the same router which forward multicast and which send IGMP query? Is ther e any solution?

Thanks for your help.
