Load Balancing
 
  VXLAN allows networks to leverage Layer 3 ECMP to efficiently distribute
      traffic loads across the network. To enable a level of entropy for load balancing on VM to VM
      traffic, ExtremeXOS derives the source UDP port in the encapsulated frame from the tenant
      packets. Transit nodes need to be configured to use appropriate mechanism to exploit the
        entropy.
configure sharing address-based custom ipv4 L3-and-L4 
configure forwarding sharing L3_L4

Note   
The Inner packet tag (tenant tag) is not used in entropy
          calculation.
