The ip classless command is for default routing only.
It does not effect the classless behavoir of a routing
protocol. Classless routing has nothing to do with
default routing. You can run a classless ip
enviroment without default routing. In fact you can
run default routing on a router with out a routing
protocol. Just use statics with the ip classless
command.
