Configuring the poison reverse function
The poison reverse function enables a route learned from an interface to be advertised through the
interface. However, the metric of the route is set to 16 (unreachable).
Follow these steps to configure poison reverse:
To do… Use the command… Remarks
Enter system view system-view ––
Enter interface view
interface interface-type
interface-number
––
Enable the poison reverse function ripng poison-reverse
Required
Disabled by default
Configuring zero field check on RIPng packets
Some fields in the RIPng packet must be zero, which 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 is discarded. If
you are sure that all packets are trustworthy, disable the zero field check to reduce the CPU processing
time.
Follow these steps to configure RIPng zero field check:
To do… Use the command… Remarks
Enter system view system-view ––
Enter RIPng view ripng [ process-id ] ––
Enable the zero field check checkzero
Optional
Enabled by default
Configuring the maximum number of equal cost routes for load
balancing
Follow these steps to configure the maximum number of equal cost RIPng routes for load balancing:
To do… Use the command… Remarks
Enter system view system-view ––
Enter RIPng view ripng [ process-id ] ––
Configure the maximum number of
equal cost RIPng routes for load
balancing
maximum load-balancing number
