The VNET tag is a global value and thus VNs on each EVN device should be provisioned with the same tag value. The valid tag value range is from 2 to 4094. EVN is supported on any interface that supports 802.1q encapsulation, for example, an Ethernet interface. Instead of adding a new field to carry the VNET tag in a packet, the VLAN ID field in 802.1q is repurposed to carry a VNET tag.
