Shim6 is work in progress and may be used as an argument to adjust adress-assignment policies sometime in the future. If we want ipv6 deployed today we have to provide a mechanism to support requirements about redundancy and independence from individual providers.
I think this hit the nail on the head. Providers (especially those non-LIR) will not accept something along the lines of SHIM6 or A.N.Other competing idea until it gives them just that -- INBOUND ROUTING INDEPENDENCE. The only way these people see achieving this is if they can announce their prefix (of whatever size or status) to each of their providers and have it form part of everybody's tables. Personally I don't have a view either way as whether it should be PI or Special Assignments or Become-A-LIR to achieve it, although everyones fees will drop with more LIRs (read: members). My view is relatively simple; either give everyone who wants one and has an AS-Number a /32 or allow /48s into the backbone table. This is of course if we actually want to give up using IPv4; without the above most providers will see it as a step backward and a bad thing (tm). I am fast gathering this is an unpopular position so I'll get the asbestos underwear ready, but in the smaller circles (read: Tier 3 and below) this is an absolute requirement. -- Best Regards, Cameron Gray Director, Netegral Limited www.netegral.co.uk | 0871 277 6845
