DHCP classless static routing support

I'm attempting to supply a network with link-local routes for multiple disjoint subnets via DHCP, by using the DHCP classless static routing option as specified in RFC 3442 (code 121 and/or 249).

This works fine with both windows and linux clients, but OS X appears to ignore the option entirely. There is very little information about OS X support for RFC3442 on google, but what I've seen suggests that it should be working - what am I doing wrong?

The routing table isn't affected at all. route monitor shows no indications that the client notices the option. I did notice that the Leopard DHCP client supplies an explicit list of option requests, CSR not being among them, so I had to force dhcpd to return it; by inspection, the returned option is exactly the same as for OSs for which it does work.

Various, Other OS, I don't use a single computer, so much as a network

Nah, not much point; we only had one macintosh computer to begin with, and we've decided it's easier to get rid of it. If Apple can't be bothered to implement the entire standard, that's now their problem.

Whether it's a feature request or a bug is more of a philosophical discussion, really; yes, it's an optional feature, but it's one that every other OS we use supports.

Unlike Baughn I do care enough to create the feature request. However, I consider this to be a significant deficiency that is bordering on a bug, particularly if Apple wishes the Mac to be taken seriously as an enterprise machine.

I also have to say that Apple's feature request mechanism is horrendously opaque with absolutely zero feedback (and it's not even obvious that the "feedback" link is the appropriate mechanism to make feature requests).

Rgds,

Guy
