Command Reference RIP Commands
ip rip authentication mode
Defines the RIP authentication mode.
ip rip authentication text-password
Enables RIP authentication, and sets the
password string of RIP plaintext authentication.
RIP data packet authentication is supported
only by RIPv2.
Defines the version of RIP packets received on
the interface.
Defines the version of RIP packets sent on the
interface.
Defines the keychain and enters keychain
configuration mode.
1.10 ip rip authentication mode
Use this command to define the RIP authentication mode. Use the no form of this command to
restore the default setting.
ip rip authentication mode { text | md5 }
no ip rip authentication mode
Configures RIP authentication as plaintext authentication.
Configures RIP authentication as MD5 authentication.
It is plaintext authentication by default.
Interface configuration mode
During the RIP authentication configuration process, the RIP authentication modes of all devices
requiring exchange of RIP routing information must be the same. Otherwise, RIP packet exchange
will fail.
If the plaintext authentication mode is adopted, but the password string of the plaintext authentication
or the associated keychain is not configured, no authentication occurs. In the same way, if the MD5
authentication mode is adopted, but the associated keychain is not configured, no authentication
occurs.
RIPv2 instead of RIPv1 supports authentication of the RIP data packet.
The following example configures the RIP authentication mode on the fastEthernet 0/1 as MD5.
Ruijie (config)#interface fastEthernet 0/1
Ruijie (config-if-FastEthernet 0/1)# ip rip authentication mode md5
