JNCIP-ENT lab 13 of 19

MVRP IGMP snooping and private VLANs

Keep trunks right with MVRP, stop a stream flooding every port with IGMP snooping, keep contractors apart with private VLANs, and find out what a filter-based VLAN does on this image.

Run this lab

It needs Standard: its 5 nodes are set to 11 vCPU and 13,312 MB in total.

In your workspace: Shared, then JNCIP-ENT JN0-650 guided labs, then 13 - MVRP IGMP snooping and private VLANs

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 11 vCPU and 13,312 MB together. Every lab plan includes every guided lab.

The scenario

A depot has two switches and a trunk between them. Someone keeps forgetting to add new VLANs to trunks, the video stream floods every port, and a contractor's laptops shouldn't see each other. You'll fix all three with features that an EX switch has for exactly this. One more feature, filter-based VLANs, is on the exam, and you'll see why you can't test it fully here.

DevicePortConnects toVLAN at the start
SW1ge-0/0/0SW2, trunkV10 only
SW1ge-0/0/1H1, 10.20.0.11/24V20, access
SW1ge-0/0/2H2, 10.20.0.12/24V20, access
SW2ge-0/0/0SW1, trunkV10 only
SW2ge-0/0/1H3, 10.20.0.13/24V20, access

V10 has tag 10 and V20 has tag 20. Note that V20 isn't on the trunk, so H1 can't reach H3.

What you’ll practise

  • Configure MVRP and read dynamic memberships
  • Write a filter-based VLAN
  • Configure IGMP snooping with an L2 querier, and measure the result
  • Build private VLANs across two switches

The tasks

  1. Let MVRP keep the trunks right
  2. Try a filter-based VLAN
  3. Stop flooding with IGMP snooping
  4. Separate hosts with private VLANs

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 13 - MVRP IGMP snooping and private VLANs 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.
