Abstract

The present application provides a port address configuration method, a forwarding device and a controller. The method includes: the first forwarding device in the SDN network sends the device feature information of the first forwarding device to the controller through a management port; The information is the first address identifier assigned by the first service port; through the first service port, the first LLDP packet sent by the second forwarding device is received, and the first LLDP packet includes the second address identifier of the second service port; if the second An address identification is greater than the second address identification, then the IP address mapped by the first address identification is used as the IP address of the first service port; if the first address identification is not greater than the second address identification, then according to the second address identification, generate the first IP address of the service port. In this way, the unified automatic configuration of the service port address of the underlay network is realized, the tedious operation of manual configuration is avoided, and the risk of configuration errors is reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular, to a port address configuration method, a forwarding device and a controller. Background technique [0002] In a software-defined network (Software Define Network, SDN), after configuring information such as the IP address, managed account, and password of each forwarding device on the controller, the controller can issue configurations related to overlay network services to the forwarding device. Thus, the forwarding service of the overlay network is automatically controlled. [0003] But for the underlay network, the establishment of the network requires the administrator to log in to each forwarding device to manually configure the underlay network parameters. For example, at the stage of forwarding device deployment and online, the administrator needs to manually configure the IP addresses of the ports connected to each other on each forwarding device. ...
