Which tunnel endpoint is shown in this output from interface Io0?

A physical tunnel endpoint refers to a VTEP (VXLAN Tunnel Endpoint) where the logical tunnel terminates on a physical device, such as a leaf switch in Cisco ACI. This endpoint uses the physical interface's IP address (or a loopback bound to a physical interface) as its source and destination for VXLAN encapsulation and decapsulation, making it a physical termination point for the overlay network.

While the tunnel endpoint is part of the overall fabric, 'fabric' describes the entire network infrastructure, not a specific type of tunnel endpoint.

A dynamic tunnel endpoint would imply that the endpoint is established on demand or changes frequently, which is not the primary characteristic being described if the answer is 'physical'.

Headend replication is a method for handling broadcast, unknown unicast, and multicast (BUM) traffic over tunnels by replicating packets at the ingress VTEP, not a classification of the tunnel endpoint itself.
