Problems solved by technology

[0004] However, with the increase of the fat AP scale or the change of the IP address of the fat AP, the IP address configuration in the fat AP needs to be continuously modified, resulting in high WLAN maintenance costs and error-prone

Abstract

The invention discloses a method for establishing a tunnel. The method comprises: when a gateway fat AP receives the IP address of the ordinary fat AP broadcast by an ordinary fat AP in any VLAN among a plurality of VLANs, it uses the IP address to communicate with the ordinary fat AP. The fat AP establishes a tunnel, so that the gateway fat AP synchronizes the online information of the wireless terminal connected to itself to the ordinary fat AP through the tunnel; broadcasts the IP address of the ordinary fat AP to other VLANs except the one In the VLAN, common fat APs in other VLANs use the IP address to establish a tunnel with the common fat AP, and synchronize the online information of the wireless terminal connected to itself to the common fat AP through the tunnel. The invention can reduce the configuration operation of the IP address, and can automatically establish the tunnel when the IP address of the fat AP changes, thereby reducing the maintenance cost of the WLAN.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for establishing a tunnel. Background technique [0002] With the increasing maturity of wireless local area network (WLAN, Wireless Virtual Local Network) technology, in many scenarios, multiple independent fat access points (AP, Access Point) belong to different VLANs (Virtual Local Area Network, virtual local area network) to build Small and medium-sized networks. [0003] At present, by configuring IP (Internet Protocol, Internet Protocol) addresses of other fat APs in the WLAN in each fat AP, all fat APs in the WLAN can establish tunnels two by two, so that after a wireless terminal goes online on a certain fat AP, the fat AP The online information of wireless terminals can be synchronized to other fat APs through the tunnel established with other fat APs. In this way, when wireless terminals roam to other fat APs, other fat APs can use the synchr...
