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.
