2.4.3 Configuring Zero Field Check on RIPng Packets
Some fields in the RIPng packet must be zero. These fields are called zero fields. With
zero field check on RIPng packets enabled, if such a field contains a non-zero value,
the entire RIPng packet will be discarded. If you are sure that all packets are trusty, you
can disable the zero field check to save the CPU processing time.
Follow these steps to configure RIPng zero field check:
