Embodiment Construction

[0036] The technical solution in the present application embodiment will be described below in conjunction with the drawings of the present application.

[0037] By this applicant studied found that the existing method of solving the L2TPV3 across network segment access to the physical interface to use the logical interface in the center-end device, establish a L2TPV3 tunnel between the branch office, and the center side interface and logic The interface is bound to the same bridge group. Among them, through the virtual interface replace the physical interface, although the resource consumption of the physical interface is reduced, as the branch is increased, the central device also needs to increase the configuration of the virtual interface, and the interface resources on the device are also consumed. At the same time, the configuration is too complicated, increasing a branch office, requires more manual add more configuration.

[0038] Among them, L2TPv3 belongs to L2TP (L2TP i...

Abstract

The present application provides a communication method, device, electronic equipment, and storage medium, which relate to the technical field of communication. The method is applied to the first network device based on L2TPv3 tunnel communication, including: receiving the first message sent by the first user equipment, the destination IP address of the inner layer IP header being the IP address and the MAC address of the second user equipment It is the MAC address of the first network device; when the routing information of the above-mentioned destination IP address and the routing exit is the tunnel entrance is queried, the above-mentioned destination MAC address is modified to the MAC address of the second network device; The layer IP header, the source IP address and the destination IP address of the outer layer IP header are respectively the start and destination IP addresses of the tunnel, so as to obtain the second message; and send the second message to the second network device through the tunnel. It makes the cross-network segment access configuration under the L2TPV3 protocol easier and improves the access efficiency.

Description

Technical field [0001] The present application relates to communication technologies, and in particular, there is a communication method, apparatus, electronic device, and storage medium. Background technique [0002] Nowadays, many companies have a cross-place office. It is more expensive through special lines, most of which are more expensive to access operators in the way using VPN (Virtual Private Network, virtual private network). For example, between enterprise central agencies and branches, the connection is established through the L2TPV3 tunnel. Such a network is similar to a virtual out of a two-layer switch, and between users and users are like they are accessible to each other on one switch interface. If you do not use other business, cross-place users must be configured as the same network segment to access each other, and cross-network segments are unable to access. [0003] The prior art allows the L2TPv3 tunnel to access the network segment to increase the configur...
