OSPF Commands

The following example prevents the Summary LSA from being advertised 

into the area 3 NSSA.

console(config-router)#area 3 stub no-summary

Use the area virtual-link command in Router OSPF Configuration mode to 

create the OSPF virtual interface for the specified area-id and neighbor 

router. To remove the link, use the no form of the command. Use the optional 

parameters to configure authentication, dead-interval, hello-interval, 

retransmit-interval and transmit-delay. If the area has not been previously 

created, it is created by this command. If the area already exists, the virtual-

link information is added or modified.
