[lisp] Move RFC7954 and RFC7955 to HISTORIC

[Luigi Iannone <[e-mail]>]

Hi all,

During the last F2F meeting in Yokohama we mentioned RFCs 7954 and 7955 to be moved to HISTORIC status.

Just for refresher those documents are about a prefix specifically reserved for EID allocation (hence non-routable).
The allocation was experimental and temporary and it did never fly.

Back in 2019 we already discussed this (see below).

It seems appropriate to have again a last call on this matter to make sure that nobody changed his mind.

As such this email starts a 4 weeks last call to move these two documents to HISTORIC status.
The text explaining the rational can be found below.

Please reply if you have any objection (and articulate the reasons for your objection).

This call ends on  10 August 2023.

Ciao

Luigi

The LISP WG concluded that very few requests have been made during three years and there was no compelling reason to extent the experiment. No further action has been taken by the LISP WG or the IETF. As such, in accordance with Section 10 of RFC 7954, RIPE NCC de-registered the existing assignments and IANA put the prefix back in the free pool (removing the entry from https://www.iana.org/assignments/iana-ipv6-special-registry).
