Step 1: Enable IPv6 In Global Mode
R1#configure terminal
R1(config)#ipv6 cef
R1(config)#ipv6 unicast-routing
Step 2: Assing IPv6 Address
R1#configure terminal
R1(config)#interface f0/0
R1(config-if)#ipv6 address a:a:a:a::1/64
Step 3: IPv6 Support OSPFv3 (Config)
R1(config)#ipv6 router ospf 1
R1(config-rtr)#router-id 1.1.1.1 (must
configured IPv4 for DR BDR election)
Ospf apply in Interface
R1(config)#interface f0/0
R1(config-if)#ipv6 ospf 1 area 0
Step 4: Create Virtual Link For Area 0 to Area 45
R2(config)#ipv6 router ospf 1
R2(config-rtr)#area 11 virtual-link 3.3.3.3
R3(config)#ipv6 router ospf 1
R3(config-rtr)#area 11 virtual-link 2.2.2.2

great, it really helps someone like me who is not a very computer literate person.
