Yep; that (having a good programming interface) makes a lot of sense
to me.  I don't think that dladm is necessarily that interface, but
something is needed.

The more interesting part (to me at least) is how to get RSVP-TE
working.  It needs to have its fingers in very deep inside OSPF (to
get the SPF tree that OSPF normally discards), but also has some
serious design issues on its own (handling many thousands of timers
efficiently is not trivial).

;-}

It sounds like we're essentially saying the same things.  I guess the
next step is writing up a proposal.  I'll send one to
opensolaris-discuss and see what happens.
