Step 3 Run:
ripng pkt-transmit { interval interval | number pkt-count }
The interval for sending RIPng Update packets and the maximum number of packets sent each
time are set on the specified interface.

3.7.4 Configuring Split Horizon and Poison Reverse

You can configure split horizon and poison reverse to prevent routing loops.
Context
Split horizon is a method of preventing routing loops by preventing the switch from advertising
a route back onto the interface from which the route is learned. On NBMA networks such as FR
networks and X.25 networks, split horizon is disabled by default.
Poison reverse is another method of preventing routing loops by enabling the switch to advertise
a route as unreachable back through the interface from which the route is learned.
If both split horizon and poison reverse are configured, only poison reverse takes effect.
Do as follows on the RIPng switch:

3.7.5 Enabling the Zero Field Check for RIPng Packets

In a RIPng packet, there are certain fields whose values must be 0. These fields are called zero
fields. If the values of these zero fields in some RIPng packets are not 0s, these RIPng packets
are ignored.
