IPv6 routing and IPv6 over IPv4 tunnels

Roll IPv6 across a provider path with static routes, OSPFv3, IS-IS and BGP, then keep two sites connected over an IPv4-only router with a tunnel.

Run this lab

It needs Standard: its 6 nodes are set to 9 vCPU and 13,824 MB in total.

In your workspace: Shared, then JNCIS-SP JN0-364 guided labs, then 11 - IPv6 routing and IPv6 over IPv4 tunnels

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 9 vCPU and 13,824 MB together. Every lab plan includes every guided lab.

The scenario

Skerry is bringing IPv6 to its Malton and York sites. The path through R2 can be upgraded. OLDCORE is an old router that stays IPv4-only, and it's the only second path. IPv4 and OSPF work everywhere. You'll add IPv6 through R2 with three routing protocols, then use OLDCORE as a backup, by carrying IPv6 across it in IPv4.

What you’ll practise

  • Configure dual-stack interfaces and static IPv6 routes
  • Run OSPFv3 and IS-IS for IPv6
  • Carry IPv6 in BGP
  • Build an IPv6 over IPv4 tunnel as a backup path

The tasks

  1. Addresses and a static route
  2. OSPFv3
  3. IS-IS for IPv6
  4. BGP for IPv6
  5. IPv6 over IPv4

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 JNCIS-SP JN0-364 guided labs.

  3. Open 11 - IPv6 routing and IPv6 over IPv4 tunnels 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.
