In a Cisco ACI Multi-Pod deployment, the spine switches within a pod should not be directly connected to the spine switches in another pod. Instead, they should be connected to an IPN (Inter-Pod Network) device that provides Layer 3 IP connectivity between the pods. This setup allows for the extension of the ACI fabric across multiple locations while maintaining a single logical fabric. The IPN device can be a router or a switch with Layer 3 capabilities that can handle the necessary routing protocols and encapsulation methods required for Multi-Pod communication. References := Implementing Cisco Application Centric Infrastructure Official Cert Guide

Enabling ARP flooding is necessary when VMs are migrated from a pre-existing network to Cisco ACI and their gateways remain in the legacy setup. This allows the ACI fabric to learn about silent hosts that do not initiate communication, ensuring that the migrated VMs can communicate with all hosts in the network, including those that are silent.
