RIPv2 is great for simple route injection. I'm talking really simple, just to avoid statics.
And there, my friend, is the crux of the matter. There's almost no place imagineable where injecting routes from RIPv2 is superior to statics.
Well, let me stimulate your imagination.. IPVPN cloud provided by carrier. Head office is ethernet into cloud. Remote sites are DSL, so terminating on LNS within cloud, and have one or more prefixes behind CPE. Pretty simple stuff. Now, when traffic comes from head office destined for a site prefix, it hits the provider gear. That provider gear will need routing information to head to a particular site. If you wanted to use statics, you will need to fill out a form each time you add/remove a prefix for a site and the provider must manage that. Its called a 'pain in the arse'. Enter RIPv2.
