This would be another alternative: http://www.space.net/~gert/RIPE/ipv6-filters.html Slightly more than 1 line, but the loose case would nuke a few more things than just filtering on 2000::/3 without requiring frequent updates. The strict case requires keeping after it for updates, and you'd probably be better off with Cymru.

Like 2000::/3. If it's not in there it's bogon, yes ? What I'm really asking, is for folks thoughts on using this - is it too restrictive ? How long until it's obsolete ? Should be a really long time no ? Again, just looking for some feedback either way. Would be very nice to have a single line ACL do this job. -- Brandon Applegate - CCIE 10273 PGP Key fingerprint: 7407 DC86 AA7B A57F 62D1 A715 3C63 66A1 181E 6996 "SH1-0151.
