2.4.4 Enabling Zero Field Check on Incoming RIPv1 Messages

Some fields in the RIPv1 message must be zero. These fields are called zero fields.
You can enable zero field check on received RIPv1 messages. If such a field contains a
non-zero value, the RIPv1 message will not be processed. If you are sure that all
messages are trusty, you can disable zero field check to save CPU resources.
Follow these steps to enable zero field check on incoming RIPv1 messages:
Enter system view
Enter RIP view
Enable zero field check on
received RIPv1 messages
