specific example

[0085] Figure 5 It is a schematic structural diagram of a T-MPLS network system, which includes network element devices NE1, NE2, NE3, and NE4, and the NE1 is connected to NE2, NE3, and NE4 respectively.

[0086] Among them, the connection between NE1 and NE2 is implemented through the physical port Gei_1 / 9 of NE1 and the physical port Gei_1 / 10 of NE2 through the optical fiber connection. Gei_1 / 9 of NE1 is in VLAN2, and the IP address corresponding to the IP interface of NE1 in VLAN2 is 192.168.100.1; Gei_1 / 10 of NE2 is in VLAN2, and the IP address corresponding to the IP interface of NE2 in VLAN2 is 192.168.100.2.

[0087]The connection between NE1 and NE3 is realized through the fiber connection between the physical port Gei_1 / 10 of NE1 and the physical port Gei_1 / 10 of NE2. Among them, Gei_1 / 10 of NE1 is in VLAN3, and the IP address corresponding to the IP interface of NE1 in VLAN3 is 192.168.200.1; Gei_1 / 10 of NE3 is in VLAN4, and the corresponding IP address of the IP i...

Abstract

The invention discloses a method and device for configuring an address resolution protocol entry. The method is: querying the IP interfaces of the first device and the second device under the VLAN where the physical port of the second device connected to the optical fiber of the first device is located; querying from the VLAN The IP interface of the first device and the second device in the same network segment; obtain the IP address corresponding to the IP interface of the second device in the network segment and the MAC address of the second device, and establish the mapping relationship between the IP address and the MAC address; add the mapping relationship to the network segment An ARP entry corresponding to the IP interface of the first device. The configuration method and device of the address resolution protocol entry provided by the present invention add the mapping relationship to the first device by establishing the mapping relationship between the MAC of the second device and the IP interface of the first device in the same VLAN and the IP address of the second device in the network segment The address resolution protocol entry ensures the correctness of the mapping relationship between the IP address and the MAC address in the address resolution protocol entry.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an address resolution protocol entry configuration method and device. Background technique [0002] In the prior art, when a network element device sends data to other network element devices, it needs to know the IP address and Media Access Control (MAC) address of the other network device. Generally, the network element equipment can know the IP address of the other network element equipment; and the MAC address needs to be obtained by searching the address resolution protocol entry (the address resolution protocol entry contains a matching IP address and MAC address); The network element device knows the MAC address of the other network element device, and can send data to the other network element device. [0003] The process for the source network element device to obtain the MAC address of the target network element device is as follows: First, the source net...
