[v6ops] Comments on draft-hazeyama-widecamp-ipv6-only-experience-01

[GangChen <[e-mail]>]

Hello authors,

Generally, the draft provided informative testing data and pointed the
failures cases. I guess some failures are related to implementations;
some are due to protocol inconsistency. It's better to make categories
so it's beneficial for the group identifying the workaround.

More detailed:

1. Some testing results have been shown in tables of section 4.2.
Wondering to known what reasons cause the data transmission failures
in the case of Frag. C => S on table 7.

2. I guess some statements on "dependency between IPv4 and IPv6
address" should be clarified further.

3. In table10, why is the hairpinning not supported? 4rd could do that
in hub&spoke mode between CE-CE communications. And 464XLAT adpoted
RFC 6146, which could support hairpinning as well.

BRs
