1.7.4. VXLAN Gateway
Logically segregated virtual networks in a data center are sometimes referred to as data center VPNs. The
QNOS VXLAN Gateway is a solution that allows VXLAN to communicate with another network, particularly a
VLAN. It offers VXLAN Tunnel Endpoint (VTEP) functionality for VXLAN tunnels on the switch.
VXLAN is a layer-3 function, IP-based technologies that prepend an existing layer-2 frame with a new IP
header, providing layer-3 based tunneling capabilities for layer-2 frames. This essentially enables a layer-2
domain to extend across a layer-3 boundary.
For the traffic from a VXLAN to use services on physical devices in a distant network, the traffic must pass
through a VXLAN Gateway.
The QNOS VXLAN Gateway feature is configurable through the CLI. It also offers an Overlay API to facilitate
programming from external agents.
Note: VxLAN feature is model dependent and not support from T3048-LY2R, T3024-P05 and T3040-
LY3
