RIP Security
By default, there is no authentication used for a RIP. However, you can configure a password for a RIP
interface. To configure a password, you must first select the authentication type (simple or MD5), and then
configure a password.
Configuring Authentication Type
If simple or MD5 password authentication is used, both switches on either end of a link must share the
same password. Use the ip rip interface auth-type command to configure the authentication type. Enter
the IP address of the RIP interface, and then enter an authentication type:
• none. No authentication will be used.
• simple. Simple password authentication will be used.
• md5. MD5 authentication will be used.
For example, to configure the RIP interface 172.22.2.115 for simple authentication you would enter:
-> ip rip interface 172.22.2.115 auth-type simple
To configure the RIP interface 172.22.2.115 for MD5 authentication you would enter:
-> ip rip interface 172.22.2.115 md5 auth-type md5
Configuring Passwords
If you configure simple or MD5 authentication you must configure a text string that will be used as the
password for the RIP interface. If a password is used, all switches that are intended to communicate with
each other must share the same password.
After configuring the interface for simple authentication as described above, configure the password for
the interface by using the ip rip interface auth-key command. Enter the IP address of the RIP interface,
and then enter a 16-byte text string. For example to configure a password “nms” you would enter:
-> ip rip interface 172.22.2.115 auth-key nms
