As for requirements for IPv6 routers, how do you think about the following requirement by rfc4443?
44443 Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification. A. Conta, S. Deering, M. Gupta, Ed.. March 2006. (Format: TXT, HTML) (Obsoletes RFC2463) (Updates RFC2780) (Updated by RFC4884) (Also STD0089) (Status: INTERNET STANDARD) (DOI: 10.17487/RFC4443)
rfc1812 says:
1812 Requirements for IP Version 4 Routers. F. Baker, Ed.. June 1995. (Format: TXT, HTML) (Obsoletes RFC1716, RFC1009) (Updated by RFC2644, RFC6633) (Status: PROPOSED STANDARD) (DOI: 10.17487/RFC1812) I suppose you never considered that in the 11 years intervening, we decided that maybe things should be done differently.
IPv6 specification is fatally broken in various ways.
Oddly enough, it doesn't seem to be fatally broken from where I am, or from where Google is, or from where Facebook is, or from where most of the cellphone companies are. You must have a different definition of "fatally broken" than the rest of us.
