RE: I-D Action: draft-ietf-6man-rfc6874bis-01.txt

[Vasilenko Eduard <[e-mail]>]

Hi Brian,
Just one small idea: does it make sense to request
"All applications claiming support for this document SHOULD choose one LLA zone as the default.
If the user would omit the zone for the literal request to fe80:: then the application SHOULD use the default zone".
It would greatly simplify life for many users because they have only one interface on the host - they would never need to investigate the name of the zone that is very OS-specific.

I do not like the request in RFC 4007:
index value zero at each scope SHOULD be reserved to mean "use the default zone"
IMHO: it is much better to omit the zone name completely to get access to the default zone.
People may not know that zone 0 has a special meaning.

Formally, what I have proposed does not contradict RFC 4007
Because the default zone could be omitted and could be 0 at the same time
(both would lead to the same default zone).

If you would say "No" to this request
Then please, repeat RFC 4007 that the default zone SHOULD be and SHOULD be "0".
Please, remind people of this fact.
Eduard

There's been no more discussion for several weeks. Can we move on to a WG Last Call?
