That would be because RIPv1 by spec only works with classfull networks.
RIPv1 has no concept of netmask's in the protocol because they didn't
exist at the time. That is why we have RIP v2 is to make RIP work with
netmasks rather than classfull networks.
So RIPv1 explicitly means classfull networks only.
RIPv2 means use netmasks.
So if the customer wants RIPv1, then they must also want classfull
networks only on their network.
