Example
The following example creates an area range for the area 1 NSSA.
console(config)#ipv6 router ospf
console(config-rtr)#area 1 range 2020:1::1/64 summarylink
area stub
Use the area stub command in Router OSPFv3 Configuration mode to create
a stub area for the specified area ID. If the area has not been previously
created, this command creates the area and then applies the stub distinction.
A stub area is characterized by the fact that AS External LSAs are not
propagated into the area. Removing AS External LSAs and Summary LSAs
can significantly reduce the size of the link state database of routers within
the stub area.
