Multi-switch Link Aggregation (MLAG)

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

Traffic from the tenant VMs that are part of an MLAG (Multi-switch Link Aggregation Group) 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 VLAN (Virtual LAN)s/VMANs that have MLAG ports.

For a configuration example, see Configuration Example for MLAG.
