One is enabled by the protocol and the other is enabled by the interface or by a routing process. The former was a hack perpetrated by yours truly to make the routing table behave like a per-host cache. I know better now, but I haven't had the time or inclination over the past four years to sit down and fix it. > 2.

Because they are created from RTF_CLONING routes and not RTF_PRCLONING routes. This may actually be a bug. -GAWollman -- Garrett A.
