For the default route to show up on R6 there is no need for the default
information originate command. You need to make R2 strictly level 2 by
changing its level under the router process instead of the interface. Once
you do that the default route should be injected automatically into R6.
Also the CLNS routing is not needed, you are doing IP routing, not CLNS
routing. It doesn't need to be turned on in global config, or be under any
of the interfaces.
