characters in simple text mode or 24 characters in cipher text mode.
md5: MD5 cipher text authentication mode.

packet format described in RFC2082.
huawei: Specifies the MD5 cipher text authentication packet to use the generic packet
format (RFC2453 standard format).
key-string: MD5 cipher-text authentication key. When input in simple text, it is a string of
1 to 16 characters, for example, 1234567. When input in cipher text, it is a string of 24
characters, for example, (TT8F]Y\5SQ=^Q`MAF4<1!!.

Description
Use the rip authentication-mode command to configure RIP-2 authentication mode
and corresponding parameters.
Use the undo rip authentication-mode command to cancel the RIP-2 authentication.
RIP-1 does not support authentication. There are two RIP authentication modes:
simple text authentication and MD5 cipher text authentication. When MD5 cipher text
authentication mode is used, there are two types of packet formats. One of them is
described in RFC 1723, which was brought forward earlier. The other format is the one
described specially in RFC 2082. The router supports both of the packet formats and
the user can select either of them on demands.
Whether you configure plain text password or cipher text password, the password must
be entered in plain text for authentication.
