JNCIP-ENT lab 14 of 19

Q-in-Q MSTP and VSTP

Share links between VLAN groups with MSTP, compare VSTP, carry a tenant in a Q-in-Q tunnel, and learn what L2PT does and what this image can show of it.

Run this lab

It needs Professional: its 5 nodes are set to 14 vCPU and 17,408 MB in total.

In your workspace: Shared, then JNCIP-ENT JN0-650 guided labs, then 14 - Q-in-Q MSTP and VSTP

Run it on Professional from £7.50 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 14 vCPU and 17,408 MB together. Every lab plan includes every guided lab.

The scenario

Northmere runs a metro network between its sites and now carries a tenant's traffic too. Today RSTP blocks one link for every VLAN, which wastes it. You'll share the load with MSTP, compare that with VSTP, and then build a Q-in-Q tunnel so that the tenant keeps its own VLAN numbers.

DevicePortConnects to
SW1ge-0/0/0, ge-0/0/1SW2 and SW3, trunks with V10 and V20
SW2ge-0/0/0, ge-0/0/1SW1 and SW3, trunks
SW3ge-0/0/0, ge-0/0/1SW1 and SW2, trunks
SW1ge-0/0/3SW3 ge-0/0/3, a separate link for the tunnel
SW1ge-0/0/2H1
SW3ge-0/0/2H2

H1 and H2 are the tenant's. Each has a tagged interface eth0.100, with 10.100.0.11/24 and 10.100.0.12/24.

What you’ll practise

  • Configure an MSTP region with two instances
  • Set per-instance roots, and read the result
  • Configure VSTP
  • Build a Q-in-Q tunnel with VLAN maps
  • Explain L2PT

The tasks

  1. Share the load with MSTP
  2. Compare VSTP
  3. Build a Q-in-Q tunnel
  4. Know what L2PT adds

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

Topology and devices

The network as it opens in EVE-NG, drawn from the lab’s own canvas, and the image each node runs.

How to open this lab

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

  2. In File Manager, open Shared, then the folder JNCIP-ENT JN0-650 guided labs.

  3. Open 14 - Q-in-Q MSTP and VSTP 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.
