Hi, Can someone point me to the latest information on the minimum IPv6 prefix providers will accept for Provider Independent IPv6 prefixes? Thanks Frank ------------------------------------ Frank P. Troy 703-396-8700 frank@troy-networks.com -------------------------------------

Ask the providers directly, it is their network thus they will have their own policies. In general though, ASNs are following: http://www.space.net/~gert/RIPE/ipv6-filters.html I don't know how common the strict/non-strict case is though, but looking at GRH (http://www.sixxs.net/tools/grh/) it seems that most ASN's are properly filtering, thus using the strict model. Of course don't forget to signup for GRH if you are going to/are participating in the IPv6 BGP and also of course sign up to ipv6-ops to keep informed about technical issues (SnR is quite high fortunately): http://lists.cluenet.de/pipermail/ipv6-ops Greets, Jeroen

The strict filter is still broken in at least one way. ipv6 prefix-list ipv6-ebgp-strict permit 2001:500::/30 ge 48 le 48 http://www.arin.net/reference/micro_allocations.html Note that there are /45's, /46's, /47's and /48's right now. The filter allows only /48's. Of note, this will break access to the F-Root name server, we announce it from both a /47 and a /48 (local peers only) in IPv6. I believe there are other issues with the strict filter, but don't have the time to track them down right now. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

Then mail Gert Doering about it, if he doesn't know he can't update it ;)

If you have them, please pass them on to Gert and possibly also spam ipv6-ops. Greets, Jeroen
