Data Center Architectures

In a five-stage IP fabric, what function does the superspine layer perform?

  • A It ensures that every leaf device has a physical connection to every spine device in the five-stage IP fabric.
  • B It establishes a common BGP autonomous system that combines multiple three-stage IP fabric spine-and-leaf nodes into one autonomous system.
  • C It creates a Layer 2 underlay network between the spine nodes and leaf nodes in the five-stage IP fabric.
  • D It interconnects the spine layers in different three-stage IP fabric pods in a data center at the same site or across different sites.
Explanation

The superspine layer interconnects the spine layers of separate three-stage IP-fabric pods, providing scalable connectivity among pods at the same data-center site or across sites. Cisco documents a super spine as a device used to interconnect multiple spine-leaf pods.
