value, RIPv1 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.
To enable zero field check on incoming RIPv1 messages:

Optional.
By default, this function 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 on an Ethernet interface, RIP compares the source IP address of the message
with the IP address of the interface. If they are not in the same network segment, RIP discards the
message.
Upon receiving a message on a serial interface, RIP checks whether the source address of the message
is the IP address of the peer interface. If not, RIP discards the message.
IMPORTANT:
Disable the source IP address check feature if the RIP neighbor is not directly connected.
To enable source IP address check on incoming RIP updates:

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:
