Working mechanisms
The VTEP uses the following process to forward an inter-site frame:
Assigns the frame to its matching VXLAN if the frame is sent between sites.
Performs MAC learning on the VXLAN's VSI.
Forwards the frame through VXLAN tunnels.
This section describes this process in detail. For intra-site frames in a VSI, the system performs typical Layer 2 forwarding, and it processes 802.1Q VLAN tags as described in "Access modes of VSIs."
