Command:
ip rip authentication key
<name-of-chain>
no ip rip authentication key-chain
Function:
Use this command to enable RIPV2 authentication on an interface and further configures the adopted key chain. The
“
no ip rip authentication key-chain
” command cancels the authentication.
Parameter:
<name-of-chain>
is the name of the adopted key chain. There may be spaces in the string. The input ends with an
enter and the string should not be longer than 256 bytes.
Command Mode:
Interface Configuration Mode.
Usage Guide:
If the authentication is only configured without configuring the key chain or password used by the interface, the
authentication does no effect. If mode has not been configured prior to configuring this command, the mode will be
set to plaintext authentication. The “no ip rip authentication key” command will cancel the authentication which only
cancels the authentication process when sending or receiving data packet other than set non authentication mode.
Example:
Switch# config terminal
Switch(config)# interface vlan 1
Switch(Config-if-Vlan1)# ip rip authentication key my key
