Claim of US Patent No. 9,769,088

1. A non-transitory computer readable medium comprising instructions, comprising functionality to:
receive, by a first switch in a multichassis link aggregation (MLAG) domain, a first media access control (MAC) frame from
an external device, wherein the external device is directly connected to the first switch, wherein the MLAG domain consists
of the first switch and a second switch;

make a first determination that the external device is not a singly-connected external device;
based on the first determination, encapsulate the first MAC frame in a first Virtual Extensible Local Area Network (VXLAN)
frame using a first virtual tunnel endpoint (VTEP), wherein the first VXLAN frame comprises a virtual VTEP Internet Protocol
(IP) address, wherein the virtual VTEP IP address is associated with the MLAG domain; and

transmit the first VXLAN frame to an IP fabric, wherein the first switch is directly connected to the IP fabric.
