What is the different of IGMP V2 and V3?
On siterouter S5300 we deploy IGMP V2 and at switch L2 connect with siterouter->we operate is IGMP V3, what will happen with multicast signalling

who can help this ?

I think all network should work in the same version otherwise igmp conflict occurs translated into no signal
