III. RIPv2 authentication
RIPv2 sets the AFI field of the first route entry to 0xFFFF to identify authentication
information. See
Figure 2-3
RIPv2 Authentication Message
z
Authentication Type: 2 represents plain text authentication, while 3 represents
MD5.
z
Authentication: Authentication data, including password information when plain
text authentication is adopted or including key ID, MD5 authentication data length
and sequence number when MD5 authentication is adopted.
Note:
z
RFC 1723 only defines plain text authentication. For information about MD5
authentication, refer to RFC2082 “RIPv2 MD5 Authentication”.
z
With RIPv1, you can configure the authentication mode in interface view. However,
the configuration will not take effect because RIPv1 does not support authentication.
2.1.5 Supported RIP Features
The current implementation supports the following RIP features.
z
RIPv1 and RIPv2
z
RIP multi-instance.
