Eric and company,

As part of this draft have you considered documenting cases where DHCPv6 is in use?  While this may not materially alter the scope of the problem statement that is outlined it may however offer implements a more efficient network event to trigger updates from.

Also where would broadband technologies fall within this document?  Wired ethernet?

Finally, if the L bit is set to 0 for on link prefixes it is conceivable that this could help to reduce some link local IPv6 multicast ND traffic.  Has this been considered?

Subject: [v6ops] IPv6 and multicast

You may want to find http://tools.ietf.org/html/draft-vyncke-6man-mcast-not-efficient-01 interesting to understand some challenges (actually wrong assumptions) posed by the use of layer-3 multicast by IPv6 (mainly for neighbor discovery) over a wired/wirelss infrastructure which has little link with the layer-3 multicast

This I-D could be the problem statement for solution I-D

Hope it helps
