Table entry generation method and device

Abstract

The invention provides a table entry generation method and device, and the method comprises the steps: forwarding a data message transmitted by opposite-end network equipment to a first host through an aggregation port when the data message is received through a first tunnel; adding a forwarding table entry in a forwarding table of a first distributed gateway, the destination address of the forwarding table entry being the address of a second host, and the egress port of the forwarding table entry being the tunnel identifier of the first tunnel; and sending a table entry synchronization message to a second distributed gateway, the table entry synchronization message comprising the address of the second host and the tunnel information of the first tunnel, so that the second distributed gateway adds the forwarding table entry to a forwarding table of the second distributed gateway according to the table entry synchronization message. According to the technical scheme of the embodiment ofthe invention, after the first distributed gateway or the second distributed gateway receives the data message through the aggregation port, the data message is sent based on the forwarding table entry, so that the data message is correctly forwarded.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular to a method and device for generating entries. Background technique

[0002] VXLAN (Virtual eXtensible Local Area Network, scalable virtual local area network) is based on IP network, using "MAC (Media Access Control, Media Access Control) in UDP (User Datagram Protocol, User Datagram Protocol)" encapsulation form of two-layer VPN ( Virtual Private Network, virtual private network) technology. Based on the existing service provider or enterprise IP network, VXLAN can provide Layer 2 interconnection for scattered sites and provide service isolation for different tenants.

[0003] In order to improve the reliability of the VXLAN network, you can use the distributed aggregation VXLAN networking mode, see figure 1 As shown, the physical port 111 and the physical port 112 of the host 11 are added to the aggregation port A, and the physical port 121 of the VTEP12 ...
