296 CHAPTER 29: IPV6 RIPNG CONFIGURATION
n
Generally, you are recommended to enable the split horizon to prevent routing
loops.
Configuring Poison
Reverse
Follow these steps to configure poison reverse:
n
■ The poison reverse function enables a route learned from an interface to be
advertised via the interface. However, the metric of the route is set to 16. That
is to say, the route is unreachable.
■ If both the split horizon and poison reverse are configured, only the poison
reverse function takes effect.
Enabling Zero Field
Check on RIPng Packets
Follow these steps to configure RIPng zero field check:
n
Some fields in the RIPng packet must be zero. These fields are called zero fields.
With the zero field check on RIPng packets enabled, if such a field contains a
non-zero value, the entire RIPng packet will be discarded.
