Refer to the exhibit. How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?

The correct answer is A. Leaf 101 forwards the ARP request to one of the proxy VTEP spines. Use of ARP Glean Messages across Pods 1. EP1 generates an ARP request to determine EP2's MAC address. 2. The local leaf does not have EP2's information but since ARP flooding is disabled it encapsulates the ARP request toward one of the Proxy Anycast VTEP addresses available on…

Exhibit

Options

ALeaf 101 forwards the ARP request to one of the proxy VTEP spines.
BPOD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2
CLeaf 101 encapsulates the ARP request into a multicast packet that is destined to 225.0.37.192.
DLeaf 101 switch consumes the ARP reply of VM2 to update the local endpoint table.

Explanation

Use of ARP Glean Messages across Pods 1. EP1 generates an ARP request to determine EP2's MAC address. 2. The local leaf does not have EP2's information but since ARP flooding is disabled it encapsulates the ARP request toward one of the Proxy Anycast VTEP addresses available on the local spine nodes (no flooding along the local multi-destination tree is allowed). infrastructure/white-paper-c11-737855.html
