Well, not really. As the video pointed out, the system was designed to leverage hierarchy to reduce routing complexity. Using the hierarchy, port number routing is only required at the level where a routes diverge on a port basis - which if you're being sensible about such a deployment would only be at the edge of the access layer. aid
