Executive Summary

FabricPath gives you a full Layer 2 vision of the network without having to rely on what your immediate peer says. Switches are informed of MAC addresses on a "need to know" basis so there are no full exchanges of routing tables as there would be in Layer 3 networks. In theory, you could move a host from one end of the network to another, and the switches would adapt on how to reach that MAC and what the best path would be from each switch's point of view.
