    Another common protocol for this design could be OSPF, with each leaf in a stubby area. Stubby areas are used to limit route propagation. The Leaf nodes connect hosts to the core and they are equivalent to the access layer. They are running Arista vEOS and support BGP to the spine. We are using 4 leaf nodes located in three different racks.
