RemarksEnter system view system-view ––Enter interface view interface interface-typeinterface-number ––Enable the split horizonfunction ripng split-horizon OptionalEnabled by defaultNote:Generally, you are recommended to enable the split horizon to prevent routing loops.II. Configuring the poison reverse functionThe poison reverse function enables a route learned from an interface to be advertisedvia the interface. However, the metric of the route is set to 16. That is to say, the route isunreachable.Follow these steps to configure poison reverse:To do... Use the command... RemarksEnter system view system-view ––Enter interface view interface interface-typeinterface-number ––Enable the poison reversefunction ripng poison-reverse RequiredDisabled by default2.4.3 Configuring Zero Field Check on RIPng PacketsSome fields in the RIPng packet must be zero. These fields are called zero fields. Withzero 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, youcan disable the zero field check to save the CPU processing time.Follow these steps to configure RIPng zero field check:To do... Use the command...
