 To redistribute externally learned OSPF routes within the ACI fabric, a Route Control Profile must be configured1. This profile allows for the control of route redistribution and the application of route maps to influence routing decisions within the fabric1.

The attribute that should be configured for each user to enable RADIUS for external authentication in Cisco ACI is cisco-av-pair. This attribute allows for the assignment of roles and permissions to users authenticated via RADIUS.

The method that the Cisco ACI fabric uses to load-balance multidestination traffic is forwarding tag trees3. This method involves assigning a forwarding tag (FTAG) to the traffic when it is forwarded within the fabric, ensuring efficient load balancing of multi-destination traffic3.

 In the scenario where Server A is connected to the Cisco ACI fabric using teamed interfaces with one active and one standby, enabling ARP flooding in the bridge domain configuration is necessary to resolve the issue that occurs when the standby interface becomes active and uses its built-in MAC address to send traffic. Enabling ARP flooding allows the fabric to learn the new MAC address without waiting for the ARP timeout, which helps to ensure that traffic continues to flow to the correct destination after a failover event1.
