In general, when devices under 2 routers communicate with each other, it is necessary to divide the 2 routers into 2 subnets staggered from each other and control a transmission path of data using a routing table. If the subnetworks defined by the 2 routers overlap (including the same subnet), the devices below the routers need to communicate with each other by building a two-layer network in the routers and virtualizing the devices below the routers into the built two-layer network.

In an embodiment, as shown in fig. 4, a 5GLAN networking method is provided, which is described by taking the networking device in fig. 1 to 3 as an example, and includes the following steps:
in step S110, an ARP query packet sent by a first communication device to a first network bridge device is intercepted, a target address of a second communication device is extracted from the ARP query packet, and the ARP query packet is sent to a corresponding ethernet card by the first network bridge device according to a preset rule;

Meanwhile, when the first network bridge device receives the ARP query packet, the first network bridge device may send the ARP query packet to the corresponding ethernet card according to a preset rule, so as to address the local IP address.
The preset rule may be that the ARP query packet is sent to an ethernet card connected to the first network bridge device, except for the ARP query packet.
In step S120, the target address is matched with a preset local outbound routing configuration table, when the matched target address is a local subnet and the outbound network card is a 5G module network card, a first ARP query result packet is constructed, and the MAC address of the target address is configured as the MAC address of the first network bridge device in the first ARP query result packet.
Referring to fig. 5, in the embodiment of the present application, a specific process of matching and matching a target address and a preset local outgoing route configuration table may include: opening the first network bridge device, reading the MAC address of the first network bridge device, extracting a target address belonging to LocalNet from a local routing table, wherein an outgoing network card is a routing item of a 5G module network card, forming a local outgoing routing configuration table, entering into an interception, matching the extracted target address in an ARP inquiry data packet with the local outgoing routing configuration table in a CIDR mode when the ARP inquiry data packet is intercepted, if the matching is successful, constructing an ARP inquiry result packet, filling relevant parameters, setting the MAC address of the target address as the MAC address of the network bridge card, and executing step S130.
Further, a destination address or a network address going out through the 5G module and a destination address or a network address going into the local subnet through the network bridge are recorded in the local routing table, and a routing entry with the destination address being the local subnet and the outgoing network card being the 5G module network card is configured in the local routing table.
The CIDR may be classless Inter-Domain Routing (classs Inter-Domain Routing), the LocalNet is used for representing a local subnet, and an address of the local subnet may be defined in a CIDR manner, and may be specifically represented by < IP >/< subnet prefix >.
In this embodiment of the present application, the local configuration routing table may be configured from a configuration interface of a networking device, or the local configuration routing table may be configured by obtaining a routing table through a remote routing configuration server, specifically, a routing entry may be read from a locally stored file, and written into the local configuration routing table through the configuration interface, or a routing record may be read from an external routing configuration server at regular time, and the local configuration routing table is refreshed.

and extracting the updated target address from the download routing configuration table, wherein the updated target address belongs to a local subnet, and the outgoing network card is a routing item of the 5G module network card so as to update the local routing configuration table.
Specifically, referring to fig. 6, a specific implementation flow of reading a route record through an external route configuration server, and refreshing the local configuration route table may be that, loading a currently stored local route configuration table, when it is determined that a route configuration server is configured, downloading the route configuration table from the route configuration server, and comparing the route configuration table with the local route configuration table, when the downloaded route configuration table has an updated configuration with respect to the local route configuration table, deleting a route entry from the local route configuration table, and the default outgoing route cannot be deleted, and overlaying the downloaded route configuration table on the locally stored route configuration table, and notifying an ARP interception module to update the local outgoing route configuration table, so as to perform matching operation with a target address through the updated local outgoing route configuration table, when the local outgoing route configuration table is not updated, timing according to a time specified in the configuration, and sleeping, and when the specified time is reached, waking up.
In step S130, the first ARP query result packet is sent to the first communication device.
In an embodiment, as shown in fig. 7, after the sending, by the first bridge device, the ARP query packet to the corresponding ethernet card according to a preset rule, the method further includes:
in step S140, sending the ARP query packet to the second communication device through a target ethernet card, where the target ethernet card is an ethernet card connected to the second communication device;

in step S160, the second ARP query result packet is sent to the first communication device.
The first communication device and the second communication device are located under the same networking device, that is, the first communication device and the second communication device are respectively connected with the first network bridge device through different Ethernet cards. The first communication device is under the same subnet as the second communication device.
In this embodiment, when a first network bridge device receives an ARP query packet sent by a first communication device, an ARP interception module detects the ARP query packet, extracts a target address from the ARP query packet, matches the target address with a preset local outbound routing configuration table, and when the target address is matched as a local subnet and an outbound network card is a 5G module network card, constructs a first ARP query result packet, and configures an MAC address of the target address as the MAC address of the first network bridge device in the first ARP query result packet.

If the ARP query result packet is a first ARP query result packet constructed by the ARP interception module, the MAC address of the target address in the first ARP query result packet is the MAC address of the first network bridge device, at this time, the first communication device may add the MAC address of the first network bridge device to the initial network request and send the initial network request to the first network bridge device, and the first network bridge device may determine that the MAC address is the first network bridge address and match the routing table, and when a routing entry of the outgoing network card is matched to the 5G module network card, the network request is forwarded through the 5G module network card, thereby implementing the connection between the first communication device and the second communication device.
