Abstract: In a method for implementing a GRE tunnel, an access device obtains an address of an aggregation gateway group including at least one aggregation gateway. The access device sends a tunnel setup request to the aggregation gateway for setting up a GRE tunnel, and the request contains an address of the access device encapsulated by using the address of the aggregation gateway group as a destination address. The access device receives a tunnel setup accept response sent back by an aggregation gateway and obtains an address of the aggregation gateway from the response. The aggregation gateway belongs to the aggregation gateway group. The access device configures the address of the aggregation gateway as a network side destination address of the GRE tunnel.

Abstract: A method for implementing a GRE tunnel is provided. The access device obtains an address of an aggregation gateway group including at least one aggregation gateway. The access device sends a tunnel setup request in which an address of the access device is encapsulated by using the address of the aggregation gateway group as a destination address. The tunnel setup request is used to request for setting up a GRE tunnel. The access device receives a tunnel setup accept response sent back by an aggregation gateway and obtains an address of the aggregation gateway from the response. The aggregation gateway belongs to the aggregation gateway group. The access device configures the address of the aggregation gateway as a network side destination address of the GRE tunnel. A dynamic setup of a GRE tunnel on an access network that uses an aggregation technology is implemented.

Abstract: A method and a device for policy based routing. The method comprises: setting interfaces of router(s) to be multiple redirection groups, the redirection groups being ordered according to a priority order; detecting interface states of interfaces in the redirection groups; and switching traffic among the multiple redirection groups according to the interface states of the interfaces in the redirection groups. With the adoption of the method and the device of the embodiments of the present disclosure, paths passing through other operators may be optionally preferred and operating costs are saved; and moreover, by configuring multi-level policy based routing, the reliability of data transmission is enhanced, and the networking of the operator is more flexible.

Abstract translation: 一种基于策略路由的方法和设备。 该方法包括：将路由器的接口设置为多个重定向组，根据优先级顺序对重定向组进行排序; 检测重定向组中接口的接口状态; 根据重定向组中接口的接口状态，在多个重定向组之间切换流量。 随着本公开的实施例的方法和装置的采用，通过其他操作者的路径可以是可选的，并节省运行成本; 此外，通过配置多级策略路由，提高了数据传输的可靠性，运营商的组网更加灵活。
