In SD-Fabric we support different topologies to meet the requirements of
different deployment sizes: from a single rack with just one leaf
-switch, or a paired-leaves for redundancy, to NxM leaf-spine fabric for multi-rack
+switch, or a paired-leaves for redundancy, to N x M leaf-spine fabric for multi-rack
deployments. For this reason, P4-UPF is realized with a "distributed" data plane
implementation where all leaf switches are programmed with the same UPF
rules, such that any leaf can terminate any GTP-U tunnel. This provides several
