I know why most of the older large ISPs use IS-IS, because it was the only option that worked at the time. But now that some router vendors have come out with workable OSPF implementations, I've been wondering which road the new ISP competitors would take. So far, they've been hiring all the engineering staff away from the older ISPs. And then the engineers set up the new network with the same skills, meaning IS-IS. But what if you started from a clean slate... If you didn't have an installed base, and didn't already know one or the other, which would you choose? Or just punt, and use iBGP.... -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
