124 CHAPTER 5: USING ROUTING PROTOCOL COMMANDS
string: Enter the MD5 cipher text authentication key.
id: Enter an MD5 cipher text authentication identifier, ranging from 1 to 255.
nonstandard: Enter to set the MD5 cipher text authentication packet to use a
nonstandard packet format (as described in RFC2082).
usual: Enter to set the MD5 cipher text authentication packet to use the general
packet format (as described in RFC1723).
Description
Using the rip authentication-mode command, you can configure the RIP-2
settings for the Switch 7700.
■ Use the rip authentication-mode simple command to configure the RIP-2
simple text authentication key.
■ Use the rip authentication-mode md5 key-string to configure the MD5
cipher text authentication key for RIP-2.
■ Use the rip authentication-mode md5 key-id command to configure the
MD5 cipher text authentication ID for RIP-2.
■ Use the rip authentication-mode md5 type command to configure the
format type of the MD5 cipher text authentication packet 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. By default, the nonstandard
packet format is used.
If you set the MD5 authentication key, but do not specify an MD5 cipher text
authentication packet
type, then the key-id is set to 1
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:
[SW7700]interface Vlan-interface 1
[SW7700-Vlan-interface1]rip version 2
[SW7700-Vlan-interface1]rip authentication-mode simple aaa
To specify the interface Vlan-interface 1 to use MD5 cipher text authentication
with the key set to “aaa” and the packet type as
nonstandard, enter the
following:
[SW7700]interface Vlan-interface 1
[SW7700-Vlan-interface1]rip version 2
[SW7700-Vlan-interface1]rip authentication-mode md5 key-string aaa
