Re: [magma] MLDv2 router in the presence of MLDv1 Multicast Address Listeners

Hi Kiyoaki Kawaguchi,

                                Yes, I would think so. Otherwise there is a
possibility of some sources getting deleted. When MLDv1 receiver is present
in the LAN, this will not be acceptable.

Thanks,
Indranil
