In a Cisco Application Centric Infrastructure (ACI) fabric, Border Gateway Protocol (BGP) Route Reflectors are used to simplify BGP configuration by reducing the number of BGP sessions required between leaf nodes in a large-scale deployment. When configuring the BGP Route Reflector policy, the following components must be configured:

D. Leaf Fabric Interface Overrides and Profiles: Leaf Fabric Interface Overrides are used to configure the interface-specific parameters of the leaf switch. In the context of BGP Route Reflectors, this includes configuring the BGP Route Reflector Cluster ID on the interfaces that connect to the Route Reflector nodes. The Leaf Fabric Interface Profile is used to apply the interface-specific configuration to a group of interfaces.

Once the Leaf Fabric Interface Overrides and Profiles are configured, the BGP Route Reflector Cluster ID can be configured on the spine switches using the following steps:

  1. Create a Route Reflector Profile: This is a container that includes the Route Reflector Node IP addresses and the Route Reflector Cluster ID.

  2. Create a Pod Policy Group: This is a container that includes the Route Reflector Profile and the Fabric Interface Profile.

  3. Attach the Pod Policy Group to the Leaf Policy Group: This associates the Route Reflector Profile and the Fabric Interface Profile with the leaf switches in the fabric.

Therefore, the correct answer is D. Leaf Fabric Interface Overrides and Profiles.
