>MCI routing breaks if you provide them with an identical >path at multiple interconnects I find this very strange, since MCI does this properly at multiple interconnects with a number of providers. Please -- if there are problems let's try to fix them in the normal fashion, rather than offer generalizations on mailing lists in what is likely to be easily misunderstood as "things don't work in general" rather than "there are specific problems which creep up from time to time".

This is something that should have been sent to engineer(a)sprint.net. Please re-send, and when it is convenient you and one of our engineering staff (or even me, if you like) can sit down and have you withdraw your more specifics and try to watch what's going on. BTW, if you have a ticket number from the INSC, management around here would love to know what it is. Sean.

I am having trouble understanding the assertion still, and am wondering what the problem is; I'm going to dive into all sorts of archived mail looking for clues about 194.45/16, but in the mean time here are some observations: Network Next Hop Metric LocPrf Weight Path *> 194.45.0.0/16 192.41.177.240 3 90 0 1800 1755 517 ? interesting prefixes *> 194.45.40.161/32 192.41.177.240 3 90 0 1800 1755 517 ? *> 194.45.120.0/26 192.41.177.240 3 90 0 1800 1755 517 ? *> 194.45.120.64/26 192.41.177.240 3 90 0 1800 1755 517 ? *> 194.45.120.128/26 192.41.177.240 3 90 0 1800 1755 517 ? all prefixes. Note that if you offered ONLY 194.45/16, rather than that AND all the more specifics, things would work fine. Have you done this? What was the problem? Why are you asserting that the problem is with SprintLink?
