In a Cisco ACI bridge domain and VRF configured with a default data-plane learning configuration, the two endpoint attributes that are programmed in the leaf switch when receiving traffic are:

Local MAC, IP (Option D)5.

Local Subnet (Option E)5. These attributes are learned by the ACI fabric through common network methods such as ARP, GARP, and ND, as well as through the data-plane. The local MAC and IP addresses are learned and used for traffic routing and bridging, while the local subnet information is used for traffic optimization and endpoint location tracking56.

In Cisco ACI fabric, MP-BGP (Multi-Protocol Border Gateway Protocol) is utilized for several purposes, one of which includes the propagation of L3Out (Layer 3 Out) routes within the fabric. Specifically, MP-BGP with VPNv4 address family (AF) is used in the ACI infra VRF (overlay-1 VRF) to distribute external routes from a border leaf to other leaf switches1. This allows for the efficient dissemination of routing information and ensures that all relevant leaf switches are aware of the routes necessary to reach external networks.

 In a Cisco ACI fabric, the spine switches are typically configured as route reflectors. This is because spine switches are central to the fabric’s architecture and are responsible for interconnecting all the leaf switches, making them ideal for reflecting BGP routes within the fabric. Therefore, the components that should be configured as route reflectors are:

Spine1 (Option A)

Spine2 (Option C)
