Cisco FabricPath
Cisco FabricPath is an innovation in Cisco NX-OS software that brings the stability and scalability of
routing to Layer 2. It provides a foundation to build a scalable fabric—a network th at itself looks like a
single virtual switch from the perspective of its users. The switched domain does not have to be
segmented anymore, providing data center–wide workload mobility. Because traffic is no longer
forwarded along a spanning tree, the bisectional bandwidth of the network is not limited, and mass ive
scalability is possible.
Cisco FabricPath introduces an entirely new Layer 2 data plane by encapsulating the frames entering the
fabric with a header that consists of routable source and destination addresses. These addresses are the
address of the switch on which the frame was recei ved and th e address of the destinatio n swi tch to whi ch
the frame is heading. From there, the frame is routed until it is reaches the remote switch, where it is
de-encapsulated and delivered in its original Ethernet format.
