To advertise a bridge domain subnet out of the ACI fabric to an OSPF neighbor, the following configuration steps are required:

Configure Subnet scope to Advertised Externally: This step involves setting the scope of the subnet within the bridge domain to be advertised externally, which allows the subnet to be propagated to external routing entities3.

Add L30ut profile to the bridge domain using Associated L30uts section: This step involves associating the bridge domain with an L3Out profile, which is necessary for the bridge domain subnet to be advertised to OSPF neighbors4.

When configuring in-band management, the new construct that must be created is a bridge domain1.

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.
