Deployment of virtual extensible local area network

A machine readable storage medium on which are stored machine readable instructions to deploy a Virtual Extensible Local Area Network (VXLAN), wherein the machine readable instructions are executable by a processor to:

• send a VXLAN information announcement message carrying identifiers of a set of VXLAN instances configured on the present VXLAN Tunnel End Point (VTEP) to the neighbor VTEP;
• receive a VXLAN information announcement message carrying the identifiers of the set of VXLAN instances configured on the neighbor VTEPs, from the neighbor VTEPs;
• if the neighbor VTEP is configured with the same VXLAN instance as the present VTEP, then set up a tunnel to the neighbor VTEP;
• associate the tunnel with the same VXLAN instance;
• if the VXLAN instances configured on the present VTEP is changed, notify the neighbor VTEPs of the VXLAN instance change;
• receive a VXLAN instance change from the neighbor VTEP;
• if a new same VXLAN instance is determined, associating the tunnel to the neighbor VTEP with the new same VXLAN instance;
• and
• if a same VXLAN instance is removed, dissociating the tunnel with the VXLAN instance.

A device for deploying a Virtual Extensible Local Area Network (VXLAN), applicable to a VXLAN Tunnel End Point (VTEP) which is a neighbor of the other VTEPs in a network where the VTEP resides, the device comprising:

• an instance information announcing unit configured to send a VXLAN information announcement message carrying the identifiers of a set of VXLAN instances configured on the present VTEP to the neighbor VTEP;
• an instance information receiving unit configured to receive VXLAN information announcement messages carrying the identifiers of VXLAN instances configured on the neighbor VTEPs, from the neighbor VTEP;
• a tunnel setting-up unit configured, if some neighbor VTEP is configured with the same VXLAN instance as the present VTEP, to set up a tunnel to the neighbor VTEP;
• an associating unit configured to associate the setup tunnel with the same VXLAN instances;
• an instance change notifying unit configured to notify the neighbor VTEP of the VXLAN instance change if the VXLAN instances configured on the present VTEP is changed
• an instance change receiving unit configured to receive a VXLAN instance change from the neighbor VTEP;
• and
• an instance change updating unit configured to associate the tunnel to the neighbor VTEP with the new VXLAN instance if a new same VXLAN instance is determined and dissociate the tunnel with the VXLAN instance if a same VXLAN instance is removed.
