1. A system comprising:
a plurality of bare metal servers;
a plurality of leaf nodes within a leaf-spine network topology;
a host routed overlay comprising at least one host virtual machine;
a leaf-server link established between a first bare metal server of the plurality of bare metal servers and a first leaf node of the plurality of leaf nodes; and
a routed backup link established between two leaf nodes of the plurality of leaf nodes;
wherein the routed backup link is pre-programmed as a backup failure path for overlay host routes facing the first bare metal server when the leaf-server link experiences a failure; and
wherein a plurality of virtual customer edge routers corresponding with the plurality of bare metal servers are configured with a same anycast gateway media access control (MAC) address to enable host virtual machine mobility across the host routed overlay.
