What is a requirement for Cisco ACI IPN to manage multidestination traffic?

 For Cisco ACI IPN (Inter-Pod Network) to manage multidestination traffic, multicast routing is a requirement. This is because multidestination traffic includes broadcast, unknown unicast, and multicast (BUM) traffic, which needs to be efficiently transported across different pods in a Cisco ACI Multi-Pod environment. Multicast routing protocols like Bidirectional Protocol-Independent Multicast (Bidir PIM) are used to handle this type of traffic1.
