Usage Guidelines

After poison reverse is configured, the route learned from an interface is also sent to the neighboring device through the same interface. The metric of this route is set to 16, indicating that the route is unreachable.

When split horizon and poison reverse are configured on the same interface, only poison reverse takes effect.

Before running the ripng poison-reverse command on an interface, run the ipv6 enable command to enable IPv6 on the interface.
