How do you ensure a router's static default route is advertised into OSPF?

The default-information originate command under the OSPF routing process is the correct way to advertise a static default route (0.0.0.0/0) into an OSPF domain. This command instructs OSPF to generate and advertise a Type 5 LSA (or Type 7 LSA in an NSSP area) for the default route. "Redistribute static subnets" is incorrect because redistribute static would advertise all static routes, not specifically the default route, and it's generally not the preferred method for default route advertisement in OSPF. Creating a default metric is insufficient; OSPF needs to be explicitly told to originate the default route. Changing the Administrative Distance of the static route only affects its preference locally on the router, not its advertisement into OSPF.
