I have a question.  Why does DHCP hand out router, net mask, broadcast address, etc. in IPv4; why don't we all just use RIP and be done with it?

You don't have to like how enterprise networks are built, but you better acknowledge that they are their own animal that have their own needs and drivers, and telling them that the way their networks are built are wrong and they need to change their whole architecture, separation of service, security model, etc. to fit your idea of perfection isn't winning friends.  You are, however, influencing people.  Perhaps not in the manner you intended.
