Abstract

The invention provides a method and a device for detecting IP address conflict of a three-layer interface. The method comprises the following steps: obtaining an IP address of a three-layer interface of a whole network in a network composed of transmission devices, wherein the IP address of the three-layer interface of the whole network comprises the IP addresses of the three-layer interfaces of different private networks composed of three-layer virtual private networks L3VPN having the same sub-network name and the IP address of the three-layer interface of a public network excluding the three-layer interfaces of the private networks; the method and the device provided by the invention are used for solving the problem in related technology that, in the case of IP address conflict of the three-layer interfaces, the IP addresses of all kinds of three-layer interfaces of the whole network cannot be detected is solved, and the IP address conflict of all kinds of three-layer interfaces of the whole network (the public network and all private networks) can be detected quickly to help a user to quickly position the IP address suffering the IP conflict.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for detecting IP address conflicts of a three-layer interface. Background technique [0002] The Internet Protocol (IP for short) address between networks is a number of a computer on the Internet. The normal situation is that every networked computer needs an IP address to communicate normally. Comparing "computer" to "telephone", then "IP address" is equivalent to "telephone number". The "telephone number" cannot be in conflict (that is, the same), and similarly, the IP address cannot be in conflict (that is, the same). [0003] When transmitting data between transmission devices, a layer-3 interface needs to be created. There are many types of layer-3 interfaces, such as: a layer-3 virtual local area network (VirtualAreaNetwork referred to as VLAN) interface, a layer-3 Ethernet port, and a layer-3 Ethernet sub-port. The Layer 3 interface of the transmission devi...
