Question

A network engineer is documenting a newly deployed software-defined fabric. She notes that VXLAN tunnels carry endpoint traffic across the data center on top of an OSPF-routed IP network that provides reachability between the switches. In this architecture, which statement correctly describes the role of the OSPF-routed IP network?

Accepted Answer

It is the underlay, providing IP connectivity that transports the encapsulated overlay traffic between fabric nodes.

Answer

It is the overlay, creating the virtual tunnels that carry endpoint traffic.
