206 CHAPTER 6: USING ROUTING PROTOCOL COMMANDS [SW5500]ospf [SW5500-ospf-1] Enable the OSPF protocol with a process ID of 120. [SW5500]router id 10.110.1.8 [SW5500]ospf 120 [SW5500-ospf-120] ospf Syntax authentication-mode ospf authentication-mode { simple password | md5 key_id key } undo ospf authentication-mode { simple | md5 } View VLAN Interface view Parameter simple password Enter a password of no more than 8 characters. key_id Enter the ID of the MD5 authentication key, in the range from 1 to 255. key Enter the MD5 authentication key. If it is input in a plain text form, MD5 key is a character string not exceeding 16 characters. And it will be displayed in a cipher text form in a length of 24 characters when display current-configuration command is executed.

Description Using the ospf authentication-mode command, you can configure the authentication mode and key between adjacent routers. Using the undo ospf authentication-mode command, you can cancel the set authentication key. By default, the interface does not authenticate the OSPF packets. The passwords for the authentication keys of routers on the same network segment must be identical. In addition, if you use this command with the authentication-mode command, you can set the authentication type of an area (see the example below). Related command: authentication-mode. Example Area 1 is where the network segment 131.119.0.0 of Interface Vlan-interface 1 is located. To set this area to support MD5 cipher text authentication, with an authentication key identifier of 15 and an authentication key of 3Com, enter the following: system-view System View: return to User View with Ctrl+Z.
