It’s an old arrangement that hasn’t been reviewed in long time … and I’m fine with that :) They used to publish their peering agreement but they don’t any longer. At the time, we met most of their requirements though (but not all)…

I ws referring to using BGP communities to limit one's Cogent transit to their customers only. ----- Mike Hammett <http://www.ics-il.com/> Intelligent Computing Solutions <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL> <http://www.midwest-ix.com/> Midwest Internet Exchange <https://www.facebook.com/mdwestix> <https://www.linkedin.com/company/midwest-internet-exchange> <https://twitter.com/mdwestix> <http://www.thebrotherswisp.com/> The Brothers WISP <https://www.facebook.com/thebrotherswisp> <https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg> _____ From: "Paul Stewart" <p...@paulstewart.org <mailto:p...@paulstewart.org> > To: af@afmug.com <mailto:af@afmug.com> Sent: Saturday, July 2, 2016 12:34:51 PM Subject: Re: [AFMUG] Cogent Not sure what there is to take advantage of … we prefer peering always over transit. PNI higher than public peering – pretty standard stuff for a lot of networks…. 75k or so routes from them on-net of which about 35k are “best route” against other peered route options to their customers.

The traffic (which is only their on-net traffic to be specific) hasn’t changed much in last couple of years, I think it’s actually dropped some – but regardless it accounts for only 3% of our traffic in total ….
