Re: [WG-BB] Study Report: CATV assignment guidline

[MAEMURA Akinori <maem@maem.org>]

Let me clarify my point.

I'm now insisting on default IP block size at initial/
bootstrap phase that is

	/23 for one 30Mbps downstream cable onto a CMTS port,
	and it could be /24 for 10Mbps one,


instead of those of the last conclusion of wg-bb that was

	/24 for one CMTS


looking forward to having your comments, colleages.

| That is why we feel like defining default size for bootstrap,
