Do you utilize the IRR, have an as-set, and put all customer AS/CIDR's into the IRR? I've honestly never heard from LVL3 about our advertisements. Other providers have varied from just needing a web form, email, phone call, or those combined with faxed LOAs. The latter gets very annoying...but maybe it is the way it should be.

Level3 pull information from a number of sources, including RIPE where we register our routes. One of the nice things about their setup is you can query a whois interface to check the filter generation: e.g. (to pick someone else's AS-MACRO at random) whois -h filtergen.level3.net RIPE::AS-DEMON Sam
