Thread Index RE: [isp-bgp] managing BGP w/ a colo company
I apologize for the solicitation, but I thought you might like to hear about one of our appliances. We have a box that will sit as an IBGP peer and update your routing tables, manage your providers, troubleshoot Sprint, Level3, Global Crossing, and Qwest before they can, provide you with detailed documentation and reporting features, and allow you to route based on latency, performance, cost, and size. Shoot me an email if you want to discuss in further detail. -----Original Message----- From: Pete Templin [mailto:petelists@...] Sent: Tuesday, March 01, 2005 1:38 PM To: isp-bgp@isp-bgp.com Subject: Re: [isp-bgp] managing BGP w/ a colo company Bob Hrbek wrote: > We receive our bandwidth from a colocation company that has peering w/ > Sprint, Qwest, Global Crossing and Level3.

Can I just add L3's AS to my > announcement a few times? :) No. If you add L3's AS to your announcement, L3 will reject your announcement ("it's got a loop in the AS path!") AND the other networks may send your traffic to L3. Your only option is to ask your direct provider what BGP communities you can add to your announcement so that inbound traffic prefers anything but Level3, and beg them to select outbound paths that are anything but Level3. Additionally, you may want to talk to your direct provider about the problems, and have them work with Level3 to try to resolve them. There could be an underlying problem that's not obvious. (We saw a strange behavior on our UUNet connection from Saturday to Monday. We were seeing a consistent and marked increase in the rate of BGP updates, from a baseline of ~180 per five minutes to a more consistent 480ish per five minutes. These kinds of things go unnoticed in provider networks. Some people think I'm nuts to worry about graphing BGP updates, but it's a great indicator of outages and problems IMHO.) pt To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
