Support of the PREF64 option in RAdv protocol (RFC 8781)

[Tom Herbers]

Hi,

has anyone already looked into adding support for the PREF64 Option
into the RAdv protocol? So far i haven't found any mention of that
option in any context with BIRD.

The purpose of the option is to inform clients which NAT64 Prefix they
should use.

It's proposed in RFC 8781 [1], but apparently not yet an official
standard.

Hoewer, there seems to be already some Client Support [2][3].


Best Regards,

Tom Herbers
