In one embodiment, a plurality of PODs is formed in a software defined networking (SDN) fabric, each POD comprising a plurality of leaf nodes and connected to a plurality of spine nodes in a spine layer of the SDN fabric. One of the plurality of PODs is designated as a super POD and link state information is provided for the entire fabric to the super POD by sending northbound advertisements in the fabric to the super POD. A disconnection is identified between a leaf node in the SDN fabric and a particular one of the spine nodes in the spine layer, based on the link state information provided to the super POD. The disconnection is repaired between the leaf node and the particular spine node in the spine layer.
