Originating and propagating a default route works well here:

router rip version 2 timers basic 3 10 0 10 passive-interface default network x.0.0.0 neighbor x.y.w.z neighbor z.y.v.w default-information originate no auto-summary

the key here is the "default-information originate".

There are a number of ways to have RIP advertise a default route.

see

RIP advertises a route to 0.0.0.0 if a gateway of last resort is selected using the ip default-network command. This network specified in the ip default-network command need not be explicitly advertised under RIP

In earlier versions of RIP, the default route created using the ip route 0.0.0.0 0.0.0.0 was automatically advertised by RIP routers. In Cisco IOS Software Release 12.0T and later, RIP does not advertise the default route if the route is not learned via RIP. It may be necessary to redistribute the route into RIP.
