Configuring zero field check on RIPng packets
Some fields in the RIPng packet header must be zero. These fields are called zero fields. You can enable zero field check on incoming RIPng packets. If a zero field of a packet contains a non-zero value, RIPng does not process the packets. If you are certain that all packets are trustworthy, disable the zero field check to save CPU resources.
To configure RIPng zero field check:
