The link state cost of the path to the area.Valid values are 0 to 16777215.
Description: The area default cost is the cost for the default route injected into an attached stub area. For all paths except Type 2 external paths, the area default cost describes the cost of the entire path.
For Type 2 external paths, the area default cost describes the cost of the portion of the path internal to the AS. This cost is calculated as the sum of the costs of the path's constituent links.
If the keyword infinity is entered, OSPF will not generate the default summary advertisement for this area in to stub areas.
Use the area area-id default-cost cost command to configure the cost of the default route injected into stub areas as the specified value.
Use the area area-id default-cost infinity command to prevent OSPF from injecting the default advertisement into stub areas.
Use the no area area-id default-cost command to configure the cost of the default route injected into stub areas as the default value of 1.
Factory Default: 1.
Command Mode: Router configuration.
Example: In the following example:
- The network commands add two areas
- The area stub commands identifies area 1.1.1.1 as a stub area
- The area default-cost command configures the cost of the default route injected by the border router into area 1.1.1.1 as 20:
router(config)#router ospf 12
router(config-router)#network 10.1.1.0 0.0.0.255 area 0
router(config-router)#network 192.12.12.0 0.0.0.255 area 1.1.1.1
router(config-router)#area 1.1.1.1 stub
