This
subnet MUST use at least the link-local prefix fe80::/10 and the
interfaces MUST be assigned IPv6 addresses of type link-local.
"
If this is conforming IPv6 then the MUST is not needed.
What do you mean by 'conforming IPv6'?
The above phrase is a clarification of existing IPv6 specs.
The spec in question is RFC 2464. I consider that to be what we need to
conform to. That spec says 'fe80::/64'. But that 64 is wrong. Hence
the clarification.
Do you disagree with it?
(the reasons why I put there /10 and not /64 are the following: LLs work
in linux with any length between 10 and 64, the ND spec does not
restrict to 64, the IANA starts at 10, and probably other reasons; there
is a recent I-D about this LL prefix length:
draft-petrescu-6man-ll-prefix-len-07).
