The ripng poison-reverse command configures poison reverse for RIPng Update packets.
The undo ripng poison-reverse command disables poison reverse for RIPng Update packets.
By default, poison reverse is disabled.

After poison reverse is enabled, the route learned from an interface can still be advertised through this interface; however, the metric of the route must be 16. When both split horizon and poison reverse are configured, only poison reverse takes effect.
The command can take effect only after IPv6 is enabled for the interface by the ipv6 enable command.
