No problem. Let me know if you have any other questions and I'll try to
help. I'm no expert, but I do have some hands-on with this platform.
If you want to enable layer-3 awareness on the optical network, the ML is
the way to go. They are basically routers running IOS on a 15454 blade.
Regards,
Mike
