The following topology has a pair of server clusters that are dual-homed to a pair of VXLAN gateways with three tenants:

VXLAN Gateways with Three Tenants

Traffic from the tenant VMs that are part of an MLAG can hash toward either gateway node. This can result in GW3 learning the same VM‘s MAC from different VTEPs. To avoid MAC toggling on remote VTEPs, ExtremeXOS requires that users configure a special local tunnel endpoint address on MLAG nodes that will be used for tenant VLANs\VMANs that have MLAG ports.

For a configuraiton example, see Configuration Example for MLAG.
