Chapter 8. IPv6 on Packet Tracer

IPv4 has 4.3 billion addresses, which may seem mindboggling. However, it took only two decades for it to reach its depletion. IPv6 has come to the rescue in the form of 128-bit addresses. Packet Tracer supports a wide array of IPv6 features. We'll start by learning how to assign IP addresses to different devices and how to configure routing between them. Finally, we'll create a setup that enables IPv6 communication over IPv4 devices.

Assigning IPv6 addresses

Starting from Packet Trace Version 6, the IP Configuration utility under the Desktop tab of end devices has an option to enter an IPv6 address. Let's begin with a simple topology consisting of two PCs and a router connected to a switch, as shown in the following screenshot:

Assigning IPv6 addresses

There are three ways of assigning IPv6 addresses to a device and we'll see each one of them.

Autoconfiguration

Autoconfiguration requires the least amount of configuration but makes it difficult to remember the IPv6 addresses. This method uses the MAC address of the device to create an IPv6 address with the FE80:: prefix. Carry out the following steps to assign IPv6 addresses using Autoconfiguration:

  1. Begin by configuring the router. Enter the interface configuration mode and enable IPv6 on the interface.
    R0(config)#ipv6 unicast-routing
R0(config)#interface FastEthernet0/0
R0(config-if)#ipv6 enable
  2. Next, we will configure a link local address and a global unicast address on this interface. We'll use eui-64 to reduce the configuration.
    R0(config-if)#ipv6 address autoconfig
R0(config-if)#ipv6 add 2000::/64 eui-64
R0(config-if)#no shutdown
  3. Verify that the interface is up and has two IPv6 addresses.
    R0>sh ipv6 interface brief
FastEthernet0/0            [up/up]
    FE80::2D0:58FF:FE65:E701
    2000::2D0:58FF:FE65:E701
  4. These IPv6 addresses may vary when you try them out, as they are based on the MAC address. Enable routing so that this router can be identified as a default gateway.
    R0(config)#ipv6 unicast-routing
  5. The configuration of the router is now done, let's move on to the PCs. Go to the Desktop tab of the PC, open IP Configuration, and under the IPv6 Configuration section, choose Auto Config. The gateway and the PC's IP address will be assigned automatically, as shown in the following screenshot:
    Autoconfiguration
  6. Use the simple PDU tool to test the connectivity; you'll see ICMPv6 packets moving between the nodes. To view the IPv6 address from the command line of PCs, use the ipv6config command.

Static IPv6

IPv6 addresses can also be assigned statically on all devices. We'll use the same topology for this section too. We'll carry out the following steps to configure IPv6 addresses statically:

  1. Begin by configuring a static IPv6 address on the router.
    R0(config)#interface fastethernet0/0
R0(config-if)#ipv6 enable
R0(config-if)#ipv6 address 2000::1/64
R0(config-if)#no shutdown
  2. Go to the Desktop tab of PC, open the IP Configuration utility, and enter an IPv6 address with the same prefix.
  3. Now use the simple PDU tool to test the connectivity. Once both the methods work fine, you can have a look at the IPv6 neighbors table. This is similar to the ARP table of IPv4.
    R0#sh ipv6 neighbor
IPv6 Address                              Age Link-layer Addr State Interface
2000::2                                     0 00E0.A39E.05C4  REACH Fa0/0
2000::3                                     0 0001.43B9.0268  REACH Fa0/0

Now that we have configured IPv6 addresses on a single network, let's configure them on more networks and enable routing between them.
