C - DHCP relay support: One of the nice functionalities offered by the ACI Multi-Pod solution is the capability of allowing auto-provisioning of configuration for all the ACI devices deployed in remote Pods. This allows those remote Pods to join the Multi-Pod fabric with zero-touch configuration, as it normally happens to ACI nodes part of the same fabric (Pod). This functionality relies on the capability of the first IPN device connected to the spines of the remote Pod to relay DHCP requests generated from a new starting ACI spines toward the APIC node(s) active in the first Pod. https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-737855.html
