area stub

Use this command to define an OSPF area as a stub area. This is an area into which Autonomous
System external ASAs will not be flooded. The no form of this command changes the stub back to
a plain area.

no area area-id stub [no-summary]
Parameters
area‐id
no‐summary
Mode
Router configuration: G3(su)‐>router(Config‐router)#

G3(su)->router(Config)#router ospf 1
G3(su)->router(Config-router)#area 10 stub

area default cost

Use this command to set the cost value for the default route that is sent into a stub area and NSSA
by an Area Border Router (ABR). The no form of this command removes the cost value from the
summary route that is sent into the stub area.

no area area-id default-cost
Parameters
area‐id

means that all destinations outside of the stub area are represented by
means of a default route.
