What is a characteristic of a Cisco ACI Multi-Pod?

A fundamental characteristic of Cisco ACI Multi-Pod is its ability to manage several physically separated ACI pods as one cohesive logical fabric, all under the control and orchestration of a single, unified Cisco APIC cluster.

Cisco ACI Multi-Pod deployments actually require multicast (PIM) within the Inter-Pod Network (IPN) to efficiently handle broadcast, unknown unicast, and multicast (BUM) traffic across pods.

While endpoint information exchange between spines in Multi-Pod uses MP-BGP with the EVPN address family, which relies on VPNv4 address families for L3 routes, stating 'VPNv4 address family' alone is less precise and not the primary defining characteristic of Multi-Pod compared to the single APIC cluster management.

Spines typically use an Interior Gateway Protocol (IGP) like OSPF or ISIS to peer with the IPN to establish reachability for TEP pool prefixes, rather than BGP to send out the TEP pool prefix directly to the IPN.
