Embodiment Construction

[0035] In order to describe in detail the technical content, the achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0036] The technical principle of the present invention: The present invention configures and enables DHCP SNOOPING through the Layer 2 switching device. DHCP SNOOPING monitors the user’s DHCP request process, creates a DHCP SNOOPING binding information table and stores it, after the Layer 2 switching device processes the binding information Upload to the three-layer switching device, according to the DHCPSNOOPING binding information, issue the three-layer engine to process routing table entries, and according to the routing table entry information, realize the network message forwarding across the virtual local area network.

[0037] See figure 1 , Is the principle block diagram of the three-layer switching system based on the two-layer DHCP SNOOPING of ...

Abstract

The invention discloses a three-layer switching system and method based on two-layer DHCP SNOOPING. The system includes a DHCP user terminal, a two-layer switching device, a three-layer switching device and a DHCP server, and is characterized in that the two-layer switching device includes an enabling The module, by enabling DHCP SNOOPING configured on the Layer 2 switching device, monitors the DHCP request process of the user terminal, creates and saves DHCP binding information; the Layer 2 switching device processes the binding information and uploads it to the Layer 3 switching device, and the third layer According to the DHCP binding information, the layer switching device delivers a routing table entry for processing by the Layer 3 engine, and forwards the network packet processed by the Layer 3 engine to the destination user terminal according to the address of the destination user terminal. The technical scheme of the present invention increases the learning method of the three-layer table entry of the switch in the DHCP environment, and effectively ensures the stability and security of the table entry.

Description

Technical field [0001] The present invention relates to the field of computer data communication, in particular to a three-layer switching system and method based on two-layer DHCP SNOOPING Background technique [0002] With the continuous improvement of switching technology in data communication, devices with Layer 3 switching functions have been widely used. Layer 3 switching devices can forward IP packets across virtual local area networks at wire speed, which is an advantage that Layer 2 switching devices do not have. [0003] The invention patent with the prior art publication number CN 101594358 A discloses a "three-layer switching method, device, system, and host machine". The method includes: receiving a network packet sent by a source virtual machine; The exchange information performs a three-layer exchange process on the network message, and generates the network message after the three-layer exchange process, the virtual link where the destination virtual machine is loca...
