Dynamic MAC Advertise through Single Home and Multihomed VTEPs
Advertise 2 MAC's through CE1 connected IXIA, dynamic MAC entries and verify MAC-table in all VTEPs.
One MAC will be dynamic local in VTEP1 and same will be remote in VTEP2 and other be dynamic local in VTEP2 and same will be remote in VTEP1.
Both MAC's will be in remote in VTEP3.

Note:
• When VTEP1 tunnel goes down, then traffic from VTEP3 will use VTEP2 for forwarding. But Traffic from Switch to VTEP1 will be lost in VTEP1 itself.
• When DUT is rebooted, access-if will be in hold down state until ESI hold timer value expiry. After ESI hold timer expiry, access-if port will be up and started learning.
• MAC Hold timer will not be applicable on ESI interface, because of mass-withdraw requirement.
• A CE can connect to maximum two nodes for multihoming, more than two nodes in a multihoming group is not supported.
• All configuration (shutdown, disable learning, disable arp/nd cache, disable arp/nd flood, map vnid, qos profiles, encapsulation) on a multihomed access port should be same on both VTEPs sharing the ESI for multihoming functionalities to work properly.
• Multiple ESI values are supported on same VTEP.
