Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manner of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] Before explaining and describing the embodiment of the present application in detail, the application scenario of the embodiment of the present application will be described.

[0044] EVPN is a VPN technology used to implement Layer 2 network interconnection. As the mainstream solution for carrying Layer 2 services, EVPN is widely used in the network design of major operators. The EVPN includes multiple PE devices, and the multiple PE devices are connected to each other. CE devices can connect to PE devices in EVPN to access EVPN.

[0045] related technologies, such as figure 1 As shown, assume that EVPN includes PE1 and PE2, CE1 and CE2 are connected to PE1, and CE3 and CE4 are connected to PE2. Combine below figure 1...

Abstract

The invention discloses an address conflict processing method and device and a storage medium, and belongs to the technical field of communication. The method is applied to an EVPN and comprises: a first PE device receiving a second MAC / IP Advertent route sent by a second PE device, and the second MAC / IP Advertent route comprising second table item information; when the first PE equipment determines that the second IP address is the same as the first IP address, determining that the second table entry information conflicts with first table entry information stored in the first PE equipment; and when the first PE device determines that the number of conflicts between the second table entry information and the first table entry information is greater than or equal to a conflict number threshold in the first period, not sending the first MAC / IP Advertisement route to the second PE device. According to the method and the device, occupation of network resources can be reduced in a table entry information conflict scene, and the network anti-attack capability can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device and storage medium for dealing with address conflicts. Background technique [0002] Ethernet Virtual Private Network (EVPN) is a virtual private network (Virtual Private Network, VPN) technology used to realize Layer 2 network interconnection. As the mainstream solution for carrying Layer 2 services, EVPN is widely used in the network design of major operators. The EVPN includes multiple provider edge (Provider Edge, PE) devices, and the multiple PE devices are connected to each other. A customer edge (Customer Edge, CE) device can connect to a PE device in the EVPN to access the EVPN. [0003] In related technologies, it is assumed that the EVPN includes a first PE device and a second PE device. The second PE device may store second entry information, where the second entry information includes a second Internet Protocol (Internet Protoc...
