Example
The following example configures the monetary default cost at 100 for stub
area 1.
console(config)#ipv6 router ospf
console(config-rtr)#area 1 default-cost 100
area nssa (Router OSPFv3)
Use the area nssa command in Router OSPF Configuration mode to
configure the specified area ID to function as an NSSA. If the area has not
been previously created, this command creates the area and then applies the
NSSA distinction. If the area already exists, the NSSA distinction is added or
modified. Use the no form of the command to remove the NSSA distinction
from the area.
