A super network router is a route whose mask length is less than its natural mask
length, for instance, 80.0.0.0/6. 80.0.0.0/6 belongs to Class-A network, but its

RIPv2-enabled device, it will learn wrong route upon receiving a super network
route for RIPv1 ignors the mask of the route message. In this case,
RIPv2-enabled device needs to disable advertising super network route on its
interface.

the interface configuration mode:
