Re: [6lo] I-D Action: draft-ietf-6lo-multicast-registration-08.txt
Hi Pascal, The draft specifies the usage of "target address" for multicast registration. To make this consistent, an update for the rules defined in Section 7.1 of RFC4861 would be required: -- 7.1. Message Validation 7.1.1. Validation of Neighbor Solicitations A node MUST silently discard any received Neighbor Solicitation messages that do not satisfy all of the following validity checks: - The IP Hop Limit field has a value of 255, i.e., the packet could not possibly have been forwarded by a router. - ICMP Checksum is valid. - ICMP Code is 0. - ICMP length (derived from the IP length) is 24 or more octets. - Target Address is not a multicast address. -- The last condition would be violated if multicast addresses are used as target address. I'd suggest that the draft updates RFC4861 Section 7.1 in a backward compatible way that would allow multicast target addresses if, and only if, the "A" or "M" flag is set.
