 In a Cisco ACI fabric, when configuring a Layer 4 to Layer 7 device for routing traffic through an external firewall connected to the inside of the fabric, the appropriate Function Type in the service graph must be selected to ensure that traffic from both POD-1 and POD-2 passes through the routed firewall when using L3Out. The “GoTo” Function Type is used in scenarios where all traffic destined for L3Out needs to be redirected through a service node like a firewall. This ensures that regardless of the source pod, traffic will traverse the service node before exiting the fabric. References: Implementing Cisco Application Centric Infrastructure Official Cert Guide

The integration of service nodes in transparent mode with a Cisco ACI Multi-Pod setup is achieved by using an active-standby firewall mode stretched across pods. This configuration ensures that the standby node takes over if the active node fails, providing high availability and seamless operation. References := Cisco ACI Multi-Pod and Service Node Integration White Paper

 To enable inter-VRF communication, one must configure settings that allow subnets to be advertised externally and establish contract interfaces between VRFs. Option B, “Enable Advertise Externally under the subnet scope,” allows subnets to be advertised outside their home VRFs. Option E, “Export the contract and import as a contract interface,” enables communication between different VRFs by creating an exportedcontract from one VRF that can be imported into another as an interface contract. References := Implementing Cisco Application Centric Infrastructure Official Cert Guide
