Configuring Zero Field Check On Ripng Packets; Configuring The Maximum Number Of Equal Cost Routes For Load Balancing - H3C S5800 Series Configuration Manual

Generally, you are recommended to enable split horizon to prevent routing loops.
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. That is to say, the route is unreachable.
Follow these steps to configure poison reverse:
To do...
Enter system view
Enter interface view
Enable the poison reverse function

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 reduce the
CPU processing time.
Follow these steps to configure RIPng zero field check:
To do...
Enter system view
Enter RIPng view
Enable the zero field check

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...
Enter system view
Enter RIPng view
Use the command...
system-view
interface interface-type
interface-number
ripng poison-reverse
Use the command...
system-view
ripng [ process-id ]
checkzero
Use the command...
system-view
ripng [ process-id ]
