We were given this packet tracer file and had to follow along with the two following YouTube videos. This is the first time I am configuring IPv6 in packet Tracer.

PC1 > Desktop > IP Configuration
Notice how the Link-Local Address is already established -- if you ping this from PC2 it should work.

Next is to configure the router to handle IPv^6.
enable > conf t > ipv6 unicast-routing

We are now going to create a link-local IPv6 address on the router g0/0 interface
- The address can be unique and short/easier to remember when manually done since it's significant locally.
enable > conf t
int g0/0 > ipv6 address FE80::1 link-local > no shut

Do the same for the g0/1 interface
Since link-local addresses are only locally significant, they don't need to identify one network from another

You should be able to ping the router interface via the link-local address of FE80::1 from PC1
Link-local addresses are not routable, so PC0 cannot communicate with PC1 or PC2 even though it can communicate with the gateway.

Unicast Configurations

All of the PCs and the router interfaces have local-link addresses, but IPv6 unicast addresses have to be assigned so cross-network communication can occur.

To do this, we will need two subnets
In Cisco Academy, the Global Unicast address is used for academic purposes is 2001:DB8 (this is the internet registry prefix) -- ISP would give the next part, in the academy it's often ACAD
- For this practice, we will use AAAA for "our company".
So far we have 2001:DB8:AAAA -- Now we need the subnet of 000A, or A
- The Network Prefix is thus 2001:DB8:AAAA:000A
  - Registry Prefix: 2001:DB8
  - ISP Assigned Site Prefix: AAAA
  - Subnet: 000A
2001:DB8:AAAA:A::1 will be the shorthand address of the first host (router interface) on Subnet A
- The one is to signify the first host of the subnet, :: to signify padding zeros
  - Host ID/Interface ID: 0000:0000:0000:0001

Assigned the Router's g0/0 interface 2001:DB8:AAAA:A::1/64, and g0/1 interface 2001:DB8:AAAA:B:1/64 Unicast Addresses

Now that the Router Interface has Unicast, the IPv6 addresses of the PCs can be automatically assigned. This is PC1.

This is PC2

This is PC0

PC1 can now ping PC0 via IPv6 addresses
