Thanks Ken, Some good stuff there, thanks. Since my original email, i think i've come up with a partial solution not requiring the far end's involvement. If not, at least it would get us into a better position to utilize the ORION network when possible. We peer over a L2 tunnel with a router down in the states threw one of our ISP's 10G links, I'm going to see if ORION will do the same with us. This would allow us to establish a BGP session directly with the ORION router, then I could use the localpref options, which may help. this problem is intermitting, most of the time things are fine. doing the above isn't going to help if path/route conditions change, but at least we'll have done all we could within reason and have a proper config. I didn't consider the reasons you mentioned related to 'fail fast', that does make a lot of sense. this is not the reason they claim this policy is in place, it is for security reasons. we access ORION via GTAnet, they are within/part of/something to do with the UoT, and we are across the street. take care, greg @Anthony Pardini <tony@pardini.org> On Jan 7, 2011, at 2:45 PM, Anthony Pardini wrote:
Firewalls aren't routers and pretty much all of them behave in the similar manner.
oh! thanks. 8) On Jan 7, 2011, at 2:37 PM, Ken Chase wrote:
It sounds like the target site has a possible misconfiguration if this is a long term issue. If they're using the open internet to get back to you and not ORION (when your packets arrived from ORION-based connection), then something is misconfigured or down. The problem is a conflict in the way BGP works and how people assume it works :) BGP is designed to get packets to where they want to go, not drop them if they're going the wrong way.
