Enabling zero field check on incoming RIPv1 messages
Some fields in the RIPv1 message must be set to zero. These fields are called "zero fields." You can
enable zero field check on incoming RIPv1 messages. If a zero field of a message contains a
non-zero value, RIP does not process the message. If you are certain that all messages are
trustworthy, disable zero field check to save CPU resources.
This feature does not apply to RIPv2 packets, because they have no zero fields.

The default setting is enabled.
Enabling source IP address check on incoming RIP updates
Perform this task to enable source IP address check on incoming RIP updates.
Upon receiving a message, RIP compares the source IP address of the message with the IP address
of the receiving interface. If they are not in the same network segment, RIP discards the message.

Configuring RIPv2 message authentication
Perform this task to enable authentication on RIPv2 messages. This feature does not apply to RIPv1
because RIPv1 does not support authentication. Although you can specify an authentication mode
for RIPv1 in interface view, the configuration does not take effect.
RIPv2 supports two authentication modes: simple authentication and MD5 authentication.
To configure RIPv2 message authentication:
