ok. i gotta ask. how does a peering point even *have* routes, let alone blow them into chunks all over the net?
Well, it has its own routes (for the shared subnet), which tends to exist in its own AS (for route collector purposes). If the peering point also has some internal infrastructure for management purposes, they may well be running an IGP. They will then want transit for this internal infrastructure. It doesn't take must misconfiguration to cause problems :) Simon -- Simon Lockhart | Tel: +44 (0)1737 839676 Internet Engineering Manager | Fax: +44 (0)1737 839516 BBC Internet Services | Email: Simon.Lockhart@bbc.co.uk Kingswood Warren,Tadworth,Surrey,UK | URL: http://support.bbc.co.uk/
