Abstract: A method for implementing a generic routing encapsulation (GRE) tunnel, an access point (AP), and a network system. The method includes establishing a Control And Provisioning of Wireless Access Points (CAPWAP) tunnel with an access controller (AC), receiving addresses of at least two gateways, establishing at least two GRE tunnels coupled to the gateways respectively according to the addresses of the at least two gateways, and selecting one of the at least two GRE tunnels to transmit data.

Abstract: A method for implementing a GRE tunnel, an access point (AP), and a gateway (GW). The method includes: the AP receives a first packet, where the first packet carries an address of the GW; configures a GRE tunnel to the GW, where a source destination of the GRE tunnel is an address of the AP, and a destination address of the GRE tunnel is the address of the GW; the AP receives a second packet sent by user equipment; performs GRE tunnel encapsulation for the second packet to form a third packet; and the AP sends the third packet to the GW by using the GRE tunnel, where the third packet carries the address of the AP. The embodiments of the present application enable efficient establishment of the GRE tunnel between the AP and the GW if there are a large quantity of APs.

Abstract translation: 实现GRE隧道的方法，接入点（AP）和网关（GW）。 该方法包括：AP接收第一分组，其中第一分组携带GW的地址; 将GRE隧道配置为GRE，其中GRE隧道的源目的地是AP的地址，GRE隧道的目的地址是GW的地址; AP接收用户设备发送的第二个报文; 对第二个分组进行GRE隧道封装，形成第三个分组; 并且AP通过使用GRE隧道向GW发送第三个分组，其中第三个分组携带AP的地址。 如果存在大量的AP，则本申请的实施例能够在AP和GW之间有效建立GRE隧道。
