interfaces tunnel <tunx> encapsulation <encapsulation>

Controls specification of a VXLAN or a VXLAN GPE tunnel for an interface.

tunnel <tunx>
The identifier of a tunnel interface. The identifier ranges from tun0 through tunx, where x is a non-negative integer.
encapsulation <encapsulation>
Where <encapsulation> is [ vxlan | vxlan-gpe ].
Virtual Extensible LAN: An encapsulation developed to support running an overlay L2 network over an existing IPv4/IPv6 network. It was originally developed to increase scalability in data center/cloud computing environments by increasing the number of isolated L2 networks from 4096 (limited by a 12-bit VLAN ID) to 16 million (using a 24-bit VXLAN ID). Traffic that belongs to the overlay network is encapsulated in a UDP packet that is routed over the underlying transport network. The payload within a VXLAN packet must be a full Ethernet frame.
Generic Protocol Encapsulation: A backwards-compatible extension to VXLAN to allow overlay traffic of several types (including but not limited to Ethernet) to be transported over the underlying IP network. The type of traffic being carried is indicated using a set of bits in the VXLAN header.
