When deploying a new Cisco ACI Multi-Pod setup, it’s crucial to ensure that the Tunnel Endpoint (TEP) pool of the new pod is routable across the Inter-Pod Network (IPN). This allows the TEP addresses to be reachable across the pods, facilitating communication between them. Additionally, increasing the Maximum Transmission Unit (MTU) for all IPN routers is necessary to support the larger frame size required by VXLAN encapsulation, which is typically above the standard Ethernet MTU of 1500 bytes.

The Cisco ACI site deployment feature that enables an engineer to control which bridge domains contain Layer 2 flooding across geographically separated data centers is Multi-Site. This feature allows for the extension of Layer 2 and Layer 3 connectivity between different locations with consistent policy enforcement5.

In the Cisco ACI environment, when an engineer wants to enforce a specific path for ICMP replies and prevent packets from taking a direct path, setting Layer 2 Unknown Unicast to Hardware Proxy on the bridge domain (BD1) is the appropriate action. This setting ensures that the unknown unicast traffic, which includes ICMP packets destined for an unknown MAC address, is forwarded to the spine proxy. The spine proxy then forwards the packets based on the endpoint table information, ensuring that the packets follow the expected path through the fabric and do not take any shortcuts or direct paths that bypass the intended routing.
