[DNA] Re: Analysis of IPv6 Relocation Delays

[Greg Daley <greg.daley@eng.monash.edu.au>]

Hi Christian,

Thanks for the draft, and your efforts in raising this for discussion.

This is definitely an important issue.

I guess that the primary issue is with regard to snooping switches,
since otherwise multicast delivery will succeed.
The problem is that a host cannot necessarily know if snooping
is in place, when it arrives at a point-of-attachment.

Perhaps it would be good to mention this in the draft (referring
also to the snoop draft).

Thanks Again,

Greg
