Configuring split horizon and poison reverse
If both split horizon and poison reverse are configured, only the poison reverse function takes effect.
Configuring split horizon
Split horizon disables RIPng from sending routes through the interface where the routes were
learned to prevent routing loops between neighbors.
As a best practice, enable split horizon to prevent routing loops in normal cases.
To configure split horizon:

Enable split horizon.
ripng split-horizon
By default, split horizon is
enabled.
Configuring poison reverse
Poison reverse enables a route learned from an interface to be advertised through the interface.
However, the metric of the route is set to 16, which means the route is unreachable.

By default, poison reverse is
disabled.
Configuring zero field check on RIPng packets
Some fields in the RIPng packet header must be zero. These fields are called zero fields. You can
enable zero field check on incoming RIPng packets. If a zero field of a packet contains a non-zero
value, RIPng does not process the packets. If you are certain that all packets are trustworthy, disable
the zero field check to save CPU resources.
