●Better utilization of available network paths in the underlying infrastructure. VLAN uses the Spanning Tree Protocol (STP) for loop prevention, which results in use of less than half of the network links in a network since redundant paths are blocked. In contrast, VXLAN packets are transferred through the underlying network based on its layer 3 header and can take complete advantage of layer 3 routing, equal-cost multipath (ECMP) routing, and link aggregation protocols to use all available paths.
