As a follow-on, I'll propose a suggested renumbering process...
1. Provide new addresses to all participants.
2. Each participant adds new addresses to their routers in accordance with their
internal maintenance procedures and announces their readiness to cut over
peering sessions.
3. Each participant reviews all announcements prior to theirs from the list and
takes responsibility for contacting those peers that have previously announced
and cutting over their peering sessions on a schedule by mutual agreement.
4. Once more than 50% of participants have announced readiness with the new
addresses, a flag day for deprecating the old addresses can be projected and
determined by the board, announced on this list. The remaining stragglers
have until that flag day to cut over their peering sessions.
In this way, there's an incentive to do your cutover as early as possible (then you
can sit back and cut over peering sessions as your peers become ready, instead
of having to reach out to each and every one of them). Additionally, it provides
for cutting peering sessions over in a controlled manner without requiring any
downtime and still on a fairly aggressive time table.
Thoughts?
