Campus VLANs, VTP, 802.1Q trunks and forwarding tables

Build the switching block of Fernhill's new Leeds warehouse: VTP to share VLANs, one static and one DTP-negotiated 802.1Q trunk, access ports, inter-VLAN routing on the distribution switch, and a look inside the MAC, ARP and CEF tables that forward every frame.

Run this lab

It needs Lite: its 6 nodes are set to 6 vCPU and 5,376 MB in total. That fits the free demo too.

The scenario

Fernhill Freight is fitting out its new Leeds warehouse. The network team has racked a distribution switch (DSW1) and two access switches (ASW1, ASW2). They're cabled but unconfigured, and the PCs already have their addresses. The design:

  • VLAN 10 STAFF (10.10.10.0/24), VLAN 20 WAREHOUSE (10.10.20.0/24), VLAN 99 MGMT (10.10.99.0/24) and VLAN 999 NATIVE (no hosts, used only as the native VLAN on trunks).
  • VLANs are created once, on DSW1, and shared with VTP version 2 (domain FERNHILL, password Fh-VTP-2026).
  • DSW1–ASW1 is a static trunk with DTP turned off; DSW1–ASW2 is negotiated with DTP, so you can compare the two.
  • DSW1 routes between the VLANs (its SVIs use .1); the access switches are managed on VLAN 99.

Topology: DSW1 Gi0/1 — ASW1 Gi0/1 · DSW1 Gi0/2 — ASW2 Gi0/1 · PC1 on ASW1 Gi1/0 · PC2 and PC3 on ASW2 Gi1/0 and Gi1/1.

What you’ll practise

  • Place a two-tier (collapsed core) switching block in the enterprise design models
  • Configure VTP version 2 server and clients and explain its risks
  • Build a static trunk and a DTP-negotiated trunk with a dedicated native VLAN and an allowed list
  • Configure access ports and SVIs for inter-VLAN routing
  • Read the MAC address table, the ARP table and the CEF FIB and adjacency tables

The tasks

  1. Find your place in the design
  2. Share VLANs with VTP
  3. Build a static trunk to ASW1
  4. Let DTP negotiate the trunk to ASW2
  5. Connect the users
  6. Route between the VLANs and manage the switches
  7. Look inside the forwarding tables

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 CCNP ENCOR 350-401 guided labs.

  3. Open 01 - Campus VLANs VTP 802-1Q trunks and forwarding tables 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.
