Two-layer VPN (Virtual Private Network, Virtual Private Network) technology of mode.VXLAN can be based on existing IP
(Internet Protocol, Internet protocol) network provides two layers of interconnection for the physical site of dispersion.
As shown in Figure 1, VXLAN networking include: VTEP (VXLAN Tunnel End Point, V XLAN endpoint of a tunnel),
GW (Gate Way, gateway) equipment, multiple VM (Virtual Machin e, virtual machine).
AC (Attachment Circuit accesses circuit) 1 interface to be connect on VTEP with VM1.VTEP can receive
The first message that VM1 is sent can carry Tag (label) 1 in the first message.If the access way of AC1 is Ethernet
(Ethernet) access way, VTEP directly carries out VXLAN encapsulation to the first message, and the first message after encapsulation is sent to GW
Equipment.The purpose equipment (can be VM2) that first message can be forwarded to by GW equipment.In addition, GW equipment can be generated VM1 pairs
ARP (Address Resolution Protocol, the address resolution protocol) list item answered, in the ARP entry record have VM1 and
The corresponding relationship of Tag (i.e. Tag1 in the first message).When GW equipment, which receives VM2, is sent to the second message of VM1, GW equipment
Tag1 can be added in the second message, and be sent to VTEP according to VM1 corresponding ARP entry.VTEP turns the second message
It is sent to VM1.
If the access way of AC1 is VLAN (Virtual Local Area Network, virtual LAN) access side
Formula, VTEP delete the Tag1 in the first message first, then, carry out VXLAN encapsulation to the first message, and by first after encapsulation
Message is sent to GW equipment, and similarly, the first message can be forwarded to VM2 by GW equipment, and generate the corresponding ARP entry of VM1, this
When, the corresponding Tag of VM1 is sky.When GW equipment receives the second message, GW equipment does not exist according to the corresponding ARP entry of VM1
Tag is added in second message, and is sent to VTEP.Tag1 is added in the second message by VTEP, and is sent to VM1.
