ACI Fabric Endpoint Learning White Paper - Cisco. Cisco.com A Cisco ACI leaf switch follows these steps to learn a local endpoint MAC address and IP address: 1. The Cisco ACI leaf receives a packet with a source MAC Address (MAC A) and source IP Address (IP A). 2. The Cisco ACI leaf learns MAC A as a local endpoint. 3. The Cisco ACI leaf learns IP A tied to MAC A if the packet is an ARP packet. 4.
Make sure you understand how Cisco ACI dataplane learning works with or without IP routing and how ARP optimizations work. Then tune the bridge domain accordingly. In most cases, you can optimize flooding by using hardware-proxy, by keeping IP routing enabled, and a subnet configured in the bridge domain.
