If all the OSPF routes are the same mask as the RIP domain then you will
get all the OSPF routes into RIP without the default-information
originate. But if the OSPF routes contain a variety of masks, say /22,
/24, /25, /27, and the RIP domain is /24, then only the /24 routes will
be propagated. To reach the other OSPF subnets via the RIP domain then
you will need a default route. This is what the default-information
originate command does.
HTH, Fred.
