IPv6 in practice lab 1 of 12

An addressing plan: SLAAC, EUI-64 and privacy addresses

Turn a /48 into a plan, then bring a staff LAN to life. Work out an EUI-64 address by hand, and watch IOS, RouterOS and Linux each configure themselves from the same router advertisement, with privacy addresses on the Linux host.

Run this lab

It needs Lite: its 5 nodes are set to 5 vCPU and 2,304 MB in total. That fits the free demo too.

The scenario

Kestrel Freight has been given 2001:db8:100::/48 by its ISP, Harbour Fibre (2001:db8::/32 is the documentation prefix, standing in for a real one). You're writing the plan and bringing up the first two LANs. Three kinds of device have to work on the staff LAN with no addresses typed in: an IOS device, a RouterOS device and a Linux PC.

What you’ll practise

  • Split a /48 into /64s, and write IPv6 addresses in their shortest correct form
  • Tell link-local, global and multicast addresses apart on a live interface
  • Work out an EUI-64 interface ID from a MAC address and check it on IOS
  • Make IOS, RouterOS and Linux configure themselves with SLAAC
  • Turn on privacy addresses on Linux and prove which address the host really uses

The tasks

  1. Start the Linux hosts
  2. Read the plan
  3. Give R1 its addresses
  4. Work out an EUI-64 address by hand
  5. SLAAC on IOS
  6. SLAAC on RouterOS
  7. SLAAC and privacy addresses on Linux

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 IPv6 in practice across vendors guided labs.

  3. Open 01 - An addressing plan - SLAAC EUI-64 and privacy addresses 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.
