A read-create integer, defaulting to 10 and configurable from 0 to 16777215, setting the metric cost assigned to the default route the ABR originates into a stub, totallyStub, nssa, or nssaTotallyStub area. This lets an admin influence how attractive the area's default route appears relative to other paths, and setting it to the maximum value of 16777215 effectively suppresses the ABR from distributing a default route into that area at all. An admin wanting to prevent an ABR from advertising a default route into a particular stub area would set this cost to the maximum value of 16777215.
