METHOD AND SYSTEM FOR VTEP REDUNDANCY IN A MULTICHASSIS LINK AGGREGATION DOMAIN

摘要

A method for transmitting MAC frames. The method includes receiving, by a first switch in the MLAG domain, a first media access control (MAC) frame from an external device, wherein the external device is directly connected to the first switch, where the MLAG domain consists of the first switch and the second switch. The method further includes making a first determination that the external device is not a singly-connected external device and based on the first determination, encapsulating the first MAC frame in a first VXLAN frame using a first virtual tunnel endpoint (VTEP), where the first VXLAN frame comprises a virtual VTEP Internet Protocol (IP) address, where the virtual VTEP IP address is associated with the MLAG domain. The method further includes transmitting the first VXLAN frame to an IP fabric, where the first switch is directly connected to the IP fabric.

1. A non-transitory computer readable medium comprising instructions, which when executed by at least one processor perform a method in a multichassis link aggregation (MLAG) domain, the method comprising:
receiving, by a first switch in the 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 the second switch; making a first determination that the external device is not a singly-connected external device; based on the first determination, encapsulating the first MAC frame in a first 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 transmitting the first VXLAN frame to an IP fabric, wherein the first switch is directly connected to the IP fabric.
