As for requirements for IPv6 routers, how do you think about the
following requirement by rfc4443?

    Originating a Packet Too Big Message makes an exception to one of the
    rules as to when to originate an ICMPv6 error message.  Unlike other
    messages, it is sent in response to a packet received with an IPv6
    multicast destination address, or with a link-layer multicast or
    link-layer broadcast address.

rfc1812 says:

    4.3.2.7 When Not to Send ICMP Errors
    An ICMP error message MUST NOT be sent as the result of receiving:
    o A packet destined to an IP broadcast or IP multicast address, or
    o A packet sent as a Link Layer broadcast or multicast, or

with reasons.

IPv6 specification is fatally broken in various ways.
