CCNAv2 Completed Packet Tracer 8.3.3.5

Greetings, and welcome to Seeseenayy.
Packet Tracer 8.3.3.5 details configuration of IPv6 for OSPF, which is (of sorts) a mix of regular OSPF with different addresses and some basic IPv6 configuration commands.
Below is a download for the provided Packet Tracer: 

Alternatively, you may read the tutorial containing the commands to complete this PT.

First, open R1. We're going to first do a command that should be repeated no matter what lab or activity you are working on. Enter your basic commands: 
R1>en
R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#ipv6 router ospf 10

This command, the last one shown above, should return with:
% IPv6 routing not enabled

Meaning we must enable unicast routing, or IPv6 Routing:
R1(config)#ipv6 unicast-routing

Then, according to the PDF, we must configure our Process ID, Router ID, and enable OSPFv3 for each interface. So lets first enable OSPF for IPv6 with the following command:

R1(config)#ipv6 router ospf 10

But wait, there's a problem! The output after this command isn't good! 

%OSPFv3-4-NORTRID: OSPFv3 process 10 could not pick a router-id,please configure manually

Okay, so we're going to have to configure the OSPF by ourselves. No big deal. Just give our router the appropriate information according to the PDF (Route, ID, Etc). Note that you shouldn't of exited the interface you get put into when entering the last command. Enter as follows: 

R1's Configuration
R1(config-rtr)#router-id 1.1.1.1   <-- Routing ID
R1(config-rtr)#int g0/0            <-- Manual Interface Conf
R1(config-if)#ipv6 ospf 10 area 0
R1(config-if)#int s0/0/0
R1(config-if)#ipv6 ospf 10 area 0
R1(config-if)#int s0/0/1
R1(config-if)#ipv6 ospf 10 area 0

So, we just repeat this process for each router device. If you need the code for the other two routers, here they are, but the process is very straight-forward.

R2's Configuration, related to R1.

R2>en
R2#conf t
R2(config)#ipv6 unicast-routing
R2(config)#ipv6 router ospf 10
%OSPFv3-4-NORTRID: OSPFv3 process 10 could not pick a router-id,please configure manually
R2(config-rtr)#router-id 2.2.2.2
R2(config-rtr)#int g0/0
R2(config-if)#ipv6 ospf 10 area 0
R2(config-if)#int s0/0/0
R2(config-if)#ipv6 ospf 10 area 0
R2(config-if)#int s0/0/1
R2(config-if)#ipv6 ospf 10 area 0

You should get something like this after configuring R2.
00:02:21: %OSPFv3-5-ADJCHG: Process 10, Nbr 1.1.1.1 on Serial0/0/0 from LOADING to FULL, Loading Done


Now, to configure R3's end...
R3>en
R3#conf t
R3(config)#ipv6 unicast-routing
R3(config)#ipv6 router ospf 10
%OSPFv3-4-NORTRID: OSPFv3 process 10 could not pick a router-id,please configure manually
R3(config-rtr)#router-id 3.3.3.3
R3(config-rtr)#int g0/0
R3(config-if)#ipv6 ospf 10 area 0
R3(config-if)#int s0/0/0
R3(config-if)#ipv6 ospf 10 area 0
R3(config-if)#int s0/0/1
R3(config-if)#ipv6 ospf 10 area 0


You should get both of these if you configured it correctly.
00:04:12: %OSPFv3-5-ADJCHG: Process 10, Nbr 2.2.2.2 on Serial0/0/1 from LOADING to FULL, Loading Done

00:04:14: %OSPFv3-5-ADJCHG: Process 10, Nbr 1.1.1.1 on Serial0/0/0 from LOADING to FULL, Loading Done

And from any router, enter the show protocols command to verify your configuration functionality:

For instance, R3:
R3#show ip protocols

IPv6 Routing Protocol is "connected"
IPv6 Routing Protocol is "ND"
IPv6 Routing Protocol is "ospf 10"
  Interfaces (Area 0)
    GigabitEthernet0/0
    Serial0/0/0
    Serial0/0/1
  Redistribution:
    None

Note "IPv6 Routing Protocol is "ospf 10"". 
That is it. Great success, eh?
