address <A.B.C.D>.

Technology Review

It is important to coordinate configuration of all routers and access servers in the stub area. The area stub

command must be configured for each of those pieces of equipment. Use the area router configuration

command with the area default-cost command to specify the cost of a default internal router sent into a

stub area by an ABR. See

area <area id> default-cost <value> on page 904 for related information.

Usage Examples

(config)#router ospf

(config-ospf)#area 2 stub
