Alexei, in the original design of the routing registries policies are based *only* on prefix (network). In ripe-181 you *cannot* use AS paths to specify policy. We did this for several reasons but mainly because using AS paths requires knowledge about non-local topology. That knowledge, if present at all, tends to age very quickly and it is very easy to shoot yourself in the foot or more vital body parts using AS path filtering. AS path capability was later added but I doubt it is in very widespread use. > Who really builds filter lists for the networks via data bases? There are a couple of providers who do it. The biggest I know of is ANS. Regards Daniel - - - - - - - - - - - - - - - - -
