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 configuration method and device of an address resolution protocol entry. The method comprises the following steps of: inquiring IP (Internet Protocol) interfaces of a first apparatus and a second apparatus in a VLAN (Virtual Local Area Network) of the physical port of the second apparatus connected with a first apparatus optical fiber; inquiring the IP interfaces of the first apparatus and the second apparatus of the same network segment from the VLAN; acquiring an IP address corresponding to the IP interface of the second apparatus in the network segment and an MAC (Media Access Control) address of the second apparatus and establishing a mapping relation of the IP address and the MAC address; and adding the mapping relation to the address resolution protocol entry corresponding to the IP interface of the first apparatus in the network segment. In the provided configuration method and the device of the address resolution protocol entry, through establishing the mapping relation between the MAC of the second apparatus and the IP address of the second apparatus which is in the same VLAN and the network segment with the IP interface of the first apparatus, and adding the mapping relation to the address resolution protocol entry of the first apparatus, the correctness of the mapping relation of the IP address and the MAC address in the address resolution protocol entry is ensured.

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...
