Anyone know *which* RFC says a packets should be routed using the most specific route in a routing table, not (for instance) the first route in the table that matches, or, for instance, using a less specific route that has a better metric? This is so basic I hardly know where to find it, but I have a (for the time being anonymous) systems vendor who really prefers the way their kernel does it .... Oddly enough it doesn't work well with subnetting.

I had a similar problem and this is what I found from 1812 this was just a brief look... E.3 Some Route Lookup Algorithms This section examines several route lookup algorithms that are in use or have been proposed. Each is described by giving the sequence of pruning rules it uses. The strengths and weaknesses of each algorithm are presented E.3.1 The Revised Classic Algorithm The Revised Classic Algorithm is the form of the traditional algorithm that was discussed in Section [E.1]. The steps of this algorithm are: 1. Basic match 2. Longest match 3. Best metric 4. Policy Neil -- Neil J. McRae. Alive and Kicking.
