Enable IPv6 Unicast Routing
Assign IPv6 addresses on an interface
Assign Area ID on interface
The ipv6 ospf area command enables OSPFv3 on an interface and places the interface in the specified 
area. Additionally, it creates the OSPFv3 process with ID on the router. OSPFv2 required two commands 
are required to accomplish the same tasks: the 
router ospf command to create the OSPF process, then the 
network area command to enable OSPFv2 on an interface. Note that the OSPFv2 network area command 
can enable OSPFv2 on multiple interfaces with the single command, whereas the OSPFv3 
ipv6 ospf area 
command must be configured on each interface that will be running OSPFv3.
