IPv6: SLAAC and dual stack with a 6in4 tunnel

Add IPv6 to a working IPv4 network. Hosts configure themselves with SLAAC, a server gets a static address, and two sites are joined across an IPv4-only provider with a 6in4 tunnel. You read link-local, global and EUI-64 addresses and see how NDP replaces ARP.

Run this lab

It needs Lite: its 6 nodes are set to 6 vCPU and 4,096 MB in total. That fits the free demo too.

The scenario

Harbour Logistics' provider has assigned it the IPv6 prefix 2001:db8:4c00::/48. You'll roll IPv6 out alongside IPv4 at head office (R1) and the depot (R3) without breaking anything. The catch: the provider core between them (R2) only carries IPv4 today, so the two IPv6 islands must be joined with a tunnel.

IPv4 already works end to end. H1 gets its IPv4 address by DHCP; the PCs are static.

What you’ll practise

  • Recognise IPv6 address types and write addresses in their shortest valid form
  • Enable IPv6 routing and configure global and link-local addresses on a router
  • Let hosts autoconfigure with SLAAC and work out an EUI-64 interface ID
  • Run IPv4 and IPv6 side by side (dual stack)
  • Carry IPv6 across an IPv4-only network with a 6in4 tunnel and static routes

The tasks

  1. Turn on IPv6 at head office
  2. Watch hosts configure themselves with SLAAC
  3. Give the server a static address and test dual stack
  4. Enable IPv6 at the depot
  5. Tunnel IPv6 across the IPv4-only provider

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder CompTIA Network Plus N10-009 guided labs.

  3. Open 04 - IPv6 - SLAAC and dual stack with a 6in4 tunnel and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
