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.
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/
