VXLAN tunnel endpoints
VXLAN creates large-scale, isolated virtual L2 networks for virtualized and multi-tenant environments
by encapsulating frames in VXLAN packets. Frame encapsulation is performed by an VXLAN tunnel
endpoint (VTEP). A VTEP originates and/or terminates VXLAN tunnels.
High-level communication in a VXLAN environment
The following illustration provides a basic view of the interaction of components in a VXLAN
environment.
FIGURE 44 High-level communication for VXLAN gateway
VXLAN gateways must be part of a two-node virtual switching cluster. In the example shown in Figure
1, RBridge 1 and RBridge 2 make up the two-node cluster. These two RBridges combine to form the
VXLAN gateway.
The current principal switch of the VXLAN gateway always communicates with the NSX controller.
This communication occurs over what is known as the management interface (depicted by the red line
in the illustration).
VXLAN gateways are supported only on the Brocade VDX 6740, 6740T, and 6740T-1G.
NOTE
VXLAN gateways must be in logical chassis cluster mode. This allows the VCS to present itself as a
single device to the NSX Controller.
