Abstract

The invention discloses a method and equipment for realizing smooth transition of authentication mode, which relate to communication field. The method includes that when the message authentication mode in network equipment needs to be modified to a second authentication mode from a first authentication mode, the second authentication mode is respectively configured on each network equipment, and a time delay is configured for the second authentication mode for determining the valid time of the second authentication mode; when the time delay of the second authentication mode is up, or the network equipment receives message sent by counterpart network equipment in second authentication mode, the message authentication mode in the network equipment is modified to the second authentication mode; now, the messages sent by network equipments all adopt the second authentication mode. During the message authentication mode modification process, the technical proposal in the invention is adopted to effectively avoid connected network equipment from disconnection due to failure authentication.

Description

technical field

[0001] The invention relates to the communication field, in particular to a method and equipment for realizing smooth transition of authentication modes. Background technique

[0002] Two network devices are interconnected. In order to enhance network security, the devices usually use text, md5 and other authentication methods. Only packets that pass the authentication are considered legal.

[0003] At present, when two network devices establishing BGP (Border Gateway Protocol, Border Gateway Protocol) neighbor relationship are configured with the same authentication method (both authentication keys are "Red"), BGP neighbors can communicate normally. , the specific process is as figure 1 as shown in:

[0004] Step 101: At time S10, when the network device router_01 sends a message to router_02, it will use the key "Red", and router_02 will use the key "Red" to perform an authentication check after receiving the message, and the authentication is successful;...
