Hi 6lo and draft authors I have some concerns about this draft replacing MLD for group registration. Having 2 different protocols for the same thing can be problematic. Hosts or routers may need to support both protocols. Is it clear which one should be used in different environments? Is there a chance that both may be used at the same time in a network? In particular, is there a chance that a router may need to simultaneously support both protocols on an L3 interface? In that case it must be considered how the two protocols interoperate. Also, we have been pushing the use of SSM in the IETF for a very long time, but this draft only supports ASM since only a group address is provided. It would be good to have some more info on the need to replace MLD. I understand there are concerns about packet loss, limited resources etc. Regards, Stig
