Fig 1-3 Enterprise that adopting virtual technology
Compare with the trandition L2/L3network design, VSF provides with multiple markedness advanta

1. VSF can increase the efficiency of operation
Only one management point, including configuration documents and gateway IP address (dispens

One logical device which is made up by multiple physical devices creates the simple topology wit
