Configuring External Connectivity for Tenants
Before you can distribute the static route to the other leaf switches on the Application Centric Infrastructure (ACI) fabric, a multiprotocol BGP (MP-BGP) process must first be operating, and the spine switches must be configured as BGP route reflectors.
To integrate the ACI fabric into an external routed network, you can configure Open Shortest Path First (OSPF) for management tenant Layer 3 connectivity.
