If it does, > the AS macro is a decent way of handling it. So, this also goes for new ASes? And you're saying that everyone that peers with you should start using AS macros in addition to aut-nums to both add new ASes and re-arrange policy for old ones. How many AS macros are there now, in the radb, ans, and ripe RR's? [i left out mci because i know how many there are, especially since it is a split db ;-] Are the AS-macros only referenced recursively after parsing the aut-num, or are they to be applied to policy independantly? How is policy to be determined for AS5757, should someone start announcing it tommorrow? In other words, say this appeared in the RADB tonight: route: 22.214.171.124/24 descr: A route that can't get everywhere origin: AS5757 mnt-by: MAINT-AS5757 changed: [email protected] 951114 source: RADB And someone, pick a provider, started announcing this to you tommorrow.
