This command works only in plaintext authentication mode.
To enable the RIP plaintext authentication function, use this command to configure the corresponding
password string, or use the associated key chain to obtain the password string. The latter takes the
precedence over the former one.
RIPv1 does not support RIP authentication but RIPv2 does.
The following example enables the RIP plaintext authentication on fastEthernet 0/1 and sets the
password string to hello.
