[v6ops] Who is stilll running 6to4 relays (Was: I-D Action: draft-ietf-v6ops-6to4-to-historic-08.txt)

[Brian E Carpenter]

With the same Bcc:

>    Internet service
>    providers SHOULD filter out routes to 192.88.99.1. 

It is pretty clear enough to me (as document editor) that there
is no consensus in the v6ops WG for this sentence, which was
added after some earlier discussion in the WG. The final
consensus has to be judged by the WG chairs, but my guess is
that we'll delete that sentence and leave the decision up to
individual operators.

(The argument is that this route helps people who are still
successfully using anycast 6to4, whether intentionally or by
default, and filtering it would hurt them without helping anyone
else.)
