I saw a switching image in there somewhere. They'll work out the shortcomings before the release, I'm sure.
The reason L2IOU perceivably "doesn't wok" is the lack of ASIC and L1 emulation.

I semi-expected it to be already available, though. -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor / Managing Partner - IPexpert On Thu, Sep 5, 2013 at 11:38 AM, Bob McCouch <[email protected]> wrote: > Except for the lack of Catalyst!
