170 CHAPTER 6: USING ROUTING PROTOCOL COMMANDS Use the rip authentication-mode simple command to configure the RIP-2 simple text authentication key. Use the rip authentication-mode md5 usual key-string to configure the MD5 cipher text authentication key for RIP-2. Use the rip authentication-mode md5 nonstandard key-string key-id command to configure the MD5 cipher text authentication ID for RIP-2. Use the undo rip authentication-mode command to cancel RIP-2 authentication. There are two RIP-2 authentication modes: simple authentication and MD5 cipher text authentication. When you use MD5 cipher text authentication mode, two types of packet formats are available. The standard format (set using the usual parameter), is described in RFC 1723. The non-standard format (set using the nonstandard parameter), is described in RFC 2082. RIP-1 does not support authentication. Related command: rip version. Example To specify the interface "Vlan-interface 1" to use simple authentication with the key set to "aaa", enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]interface Vlan-interface 1 [SW5500-Vlan-interface1]rip version 2 [SW5500-Vlan-interface1]rip authentication-mode simple aaa To specify the interface Vlan-interface 1 to use MD5 authentication with the key string as "aaa" and the packet type set to usual, enter the following: [SW5500]interface Vlan-interface 1 [SW5500-Vlan-interface1]rip version 2 [SW5500-Vlan-interface1]rip authentication-mode md5 key-string aaa [SW5500-Vlan-interface1]rip authentication-mode md5 type nonstandard To set MD5 authentication on Vlan-interface 1 with the key string set to "aaa" and the packet type set to usual, enter the following: [SW5500]interface Vlan-interface 1 [SW5500-Vlan-interface1]rip version 2 [SW5500-Vlan-interface1]rip authentication-mode md5 usual aaa rip input Syntax rip input undo rip input View Interface View
