Problems solved by technology
Although this method can enable PC1 to access PC2, there are two shortcomings: one is that the message sent by PC1 to PC2 goes to the third layer, that is, the IP layer to search for the route, and after the routing entry is found, the three-layer forwarding is performed
In fact, PC1 and the router are both connected devices of the home gateway. The message sent by PC1 to the router can be forwarded directly on the second-layer bridge, and there is no need to go up to the third layer, that is, the IP layer to find routing entries; the second problem is, Once the address obtained by the router WAN connection changes, the user must manually configure the static route, which brings inconvenience to the user

Embodiment Construction
[0043]The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0044] figure 1 is a flow chart of a network interconnection method provided by an embodiment of the present invention, such as figure 1 shown, including:
[0045] Step S101: The gateway access device determines whether the data message is sent to the external network or to a router connected to the home gateway according to the destination IP address of the data message and the static routing entry issued by the home gateway;
[0046] Step S102: When it is judged that the data message is sent to the external network, the gateway access device sends the data message to the home gateway for forwarding to the external network;
[0047] Step S103: When i...

The invention discloses a method and device for network interconnection, and relates to the technical field of broadband access communication. Whether the data message is sent to the external network or to the router connected to the home gateway; when it is judged that the data message is sent to the external network, the gateway access device sends the data message to the The home gateway of the network; when it is determined that the data message is sent to the router connected to the home gateway, the gateway access device sends the data message to the router for network interconnection.
Description
technical field [0001] The invention relates to the technical field of broadband access communication, in particular to a method and device for network interconnection. Background technique [0002] The home gateway is a network device located inside the user's home. It is the hub connecting the external network and the user's home network, and provides rich and efficient network services for people's daily life. In order to increase the number of devices connected to the home gateway, or to improve the coverage and signal strength of the wireless network, many users will connect a router to the LAN (LocalArea Network, local area network) port of the home gateway. The router is placed relatively far away from the home gateway. At one point, some of the access devices are directly connected to the home gateway, and the other part of the access devices are connected to the home gateway through a router. The specific scene is attached image 3 As shown, the home gateway assign...
