add ospf stub

Use add ospf stub to add a stub area. This is an area where there is a single exit point from that area, or where routing to outside the area does not take an optimal path. Adding a stub area allows you to reduce the topological database size inside an area, and reduces the memory requirements of routers inside that area.

Object	Parameter	Description
<AreaID>	:IPAddress	The Area ID uses the same format as an IP Address, but defines a summarization point for Link State Advertisements. It is an OSPF Area identifier.
<Metric>	:INTEGER (0. .'FFFFFF'h)	Indicates the metric to be advertised.

Note: The only metric used is the stub metric configured on the area's border router. This metric is used for the default route being advertised into the stub area.
