It is in conjunction with a route server. The filtering I meant would be that network A wants the IX to drop all advertisements to them from network B. Normally solved by network B putting a community on their routes to not advertise to network A, but network B doesn't want to do one-off configs. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Andy Davidson" <andy@nosignal.org> To: "Mike Hammett" <nanog@ics-il.net> Cc: "NANOG list" <nanog@nanog.org> Sent: Thursday, October 19, 2017 1:20:08 AM Subject: Re: AS36040 Prefix Limits Hi, Mike On 18/10/2017, 18:39, Mike Hammett <nanog@ics-il.net> wrote:
I am looking for someone that can speak authoritatively regarding AS36040's ability to change their own prefix limits, prefix filtering, etc. My current contact is advising the IX to do the filtering for them, which is not something IXes should be doing.
Unless this is in conjunction with a multilateral peering session (“route-server”), when prefix-filtering is something that the IXP very much should be doing. Andy
