From: "joel jaeggli" <joelja@bogus.com> you take all the useful information that an IGP could be (or is) providing you, and then you ignore it and do something else.
Well, I tell you what. My perception of where this was a good idea is the use case a recent client might have for it: Two consumer-grade uplinks (FiOS 150 and RR 100, specifically); primary application is callcenter, VoIP to a service provider Elsewhere. I would set it up so that all the VoIP and callcenter web traffic went over FiOS *until it failed*, and everything else went Road Runner *unless it failed*. This keeps the general traffic out of the hair of the latency/PPS sensitive traffic whenever possible. Is that not policy-based routing? Why is it bad? Cheers, -- jra -- Jay R.
