Abstract
Description
technical field
[0001] The invention relates to the field of communication technology, in particular to a method, system and authentication server for establishing a virtual extensible local area network tunnel. Background technique
[0002] VxLAN (Virtual Extensible LAN, Virtual Extensible Local Area Network) technology is an international technical standard formulated by the IETF (The Internet Engineering Task Force, Internet Engineering Task Force) standard organization. Protocol) tunnel encapsulates the user's Layer 2 message and transmits it in the Layer 3 IP network. Using this technology, a user-defined Layer 2 network can be built across the Layer 3 IP network. Private addresses, even non-IP packets. Since VxLAN technology is a stateless tunnel technology, the key issue in establishing a tunnel is how to configure the tunnel IP address and VNI (VxLAN Network Identifier, VxLAN Network Identifier) ββon the network side at the tunnel entry point.
[0003] At present, ...
