Not directly related to this issue, but... There was also some discussion at MAGMA working group that if the edge router starts to filter MLD Reports coming from a host (host authorization), it would be nice to notify the host that such filtering is applied, e.g. with ICMPv6 Administratively Prohibited. MLD Reports are however sent to multicast address and thus the router can't use ICMPv6 (spec says that error message MUST NOT be sent as a result of receiving a packet destined to an IPv6 multicast address). So, what about one more exception to the ICMPv6 spec in addition to the Packet Too Big and Parameter Problem messages?
