Re: towards phasing out the 6bone

[Robert Fink <bobfink@gmail.com>]

Jinmei,

Your point is a valid one. I will start sending regular reminders to
the 6bone mail list on 1 Jan 06 and repeat them regularly till 6/6/06.

In spite of that, many nets will ignore these warnings and thus have
to take the consequences when all 3FFE routes are filtered out as of
6/6/06, and I guess that's just the way it will have to be.

Thanks,

Bob
