This lab tests numerous combinations of OSPF area parameters. It tests:

* Stub and NSSA areas
* Insertion of default route into stub/NSSA areas
* Default route cost in stub/NSSA area
* Suppression of inter-area routes in stub/NSSA area
* Area ranges (including explicit range cost) and suppressed ranges
* Summarization and suppression of NSSA routes
* Configuration of VRF instances
