Example
The following example prevents the Summary LSA from being advertised
into the area 3 NSSA.
console(config-router)#area 3 stub no-summary
area virtual-link
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.
