Dear database managers, I notice a loop in the followings AS-MACRO, in fact AS-TELEDANMARKINTERNATIONAL is calling AS-TLI which is calling AS-TELEDK which is calling AS-TELEDANMARKINTERNATIONAL. (and all that make that our automatic filter generation tool fails) Could you correct those macro and will the Ripe database management provide any control on that kind of loop ?

I have seen those elsewhere, such as at AS-UNI. I don't think it is entirely avoidable. I don't know if it is illegal either, albeit it ought to be, as the construction doesn't make sense. Consider letting your automation keep a list of previously expanded macros so that it doesn't do it again. Peter B. Juul, Uni-C (PBJ255-RIPE)

A simple check to avoid expanding a macro you allready have expanded would solve that.

Not possible, as Talkline and Tele Danmark provide transit services for each other, this would require a total new layout of the AS macro's. And I cannot see that a loop should be such a bad thing, the check is very simple. /Jesper

Even if the check is very simple, even if they provide transit service to each other, as Peter said "the construction doesn't make sense", it is not logic !!!! Gilles

Have a look at other macro's lots have this construction - it's not ideal, but it's not a huge problem either. This is by far the easist way to constructing such macro's, though a setup like AS-TELEDK - AS-TLICUSTOMERS - AS-TELEDKCUSTOMERS - others AS-TLI - AS-TLICUSTOMERS - AS-TELEDKCUSTOMERS - others would be more clean, but it's not what we've implemented at this time. /Jesper -- Jesper Skriver, jesper(at)skriver(dot)dk - CCIE #5456 Work: Network manager @ AS3292 (Tele Danmark DataNetworks) Private: Geek @ AS2109 (A much smaller network ;-) One Unix to rule them all, One Resolver to find them, One IP to bring them all and in the zone to bind them.
