158 CHAPTER 6: USING ROUTING PROTOCOL COMMANDS
current-configuration command is executed. Inputting the MD5 key in cipher
text form with 24 characters long is also supported.
nonstandard: Enter to set the MD5 cipher text authentication packet to use a
packet format (as described in RFC2082).
key-id Enter an MD5 cipher text authentication identifier, ranging from 1 to 255.
Description
Use the rip authentication-mode command to configure the RIP-2
authentication mode and its parameters for the Switch 4500.
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:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]interface Vlan-interface 1
[4500-Vlan-interface1]rip version 2
[4500-Vlan-interface1]rip authentication-mode simple aaa
[4500-Vlan-interface1]quit
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:
[4500]interface Vlan-interface 1
[4500-Vlan-interface1]rip version 2
[4500-Vlan-interface1]rip authentication-mode md5 key-string aaa
[4500-Vlan-interface1]rip authentication-mode md5 type nonstandard
