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
- 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
PREFIX-based filtering instead, just with the COMMUNITY-based route
control. RELCOM does both PREFIX (always except upstream links) and AS
This means _it's highly recommended to keep your network objects in the
registry data bases in order_. But it depends from the topology.
