It depends of the service provider etc. When we add new customer with his own AS and network, we (here) must: - add his AS into our AS MACRO in RIPE data base, because a dozen providers here and in Europe, just as (for example) MCI in USA use this (and RADB) data base for the AS-based filtering; - send this AS to some our peers and upstream provider because they build AS-based filetsr manually (through it tends to the RIPE or RADB usage instead) - send the PREFIX (not AS) to some providers because they use prefix-based filtering (at least UUnet does so). (all this except (1) is doing by the programs, of course - we update RIPE and generate everything from the RIPE). I (personally) am thinking AS-based filtering is useless and it's safer to do PREFIX-based filtering instead, just with the COMMUNITY-based route control. RELCOM does both PREFIX (always except upstream links) and AS (sometimes) filtering. This means _it's highly recommended to keep your network objects in the registry data bases in order_. But it depends from the topology. Alex.
