RIP Commands 329
User Guidelines
This command is equivalent to rip default-route originate . Note that this is an origination of
a default route with the given metric. Setting the value of the metric to 0 is the same as
negating the command. An interface on which this command has been configured does not
accept
default route advertisement, in order to prevent a possible loop on the default route.
NOTE: This command will be deprecated in a future version.
Example
The following example applies an offset of 5 to generate a default route to RIP on IP address
100.1.1.1.
rip authentication
The rip authentication interface configuration command enables authentication for Routing
Information Protocol (RIP) Version 2 packets and specifies the authentication type. To prevent
authentication, use the
no form of this command.
Syntax
rip authentication { text text | md5 name-of-chain }
no rip authentication
• text text —Clear text authentication. The string can contain from 1 to 16 uppercase and
lowercase alphanumeric characters.
•
md5 name-of-chain —Keyed Message Digest 5 (MD5) authentication.
Default Configuration
No authentication is provided for RIP packets.
Command Mode
IP Interface Configuration mode
User Guidelines
It is possible to configure undefined keys for authentication, with the assumption that they
will later be defined. In such cases, a message is generated stating that the key does not exist.
