An engineer is troubleshooting fabric discovery in a newly deployed Cisco ACI fabric and analyzes this output: Which ACI fabric address is assigned to interface lo1023?

The correct answer is C. Fabric tunnel endpoint. In addition to loopback 0 interfaces, ACI creates loopback 1023 interfaces on all leaf switches. A loopback 1023 interface is used for assignment of a single fabricwide pervasive IP address called a fabric tunnel endpoint (FTEP) address. The FTEP address represents the entire…

Explanation

In addition to loopback 0 interfaces, ACI creates loopback 1023 interfaces on all leaf switches. A loopback 1023 interface is used for assignment of a single fabricwide pervasive IP address called a fabric tunnel endpoint (FTEP) address. The FTEP address represents the entire fabric and is used to encapsulate traffic in VXLAN to an AVS or AVE virtual switch, if present.
