Inter-VLAN routing on a Layer 3 switch: SVIs and routed ports

Turn a distribution switch into the gateway for every VLAN with SVIs, connect it to the WAN router through a routed port, and route the whole site to an 'Internet' address with a default route and a summary route back.

Run this lab

It needs Lite: its 5 nodes are set to 5 vCPU and 5,120 MB in total. That fits the free demo too.

The scenario

Ridgeway Distribution has outgrown router-on-a-stick. A new distribution switch (DSW1) will route between the VLANs itself, and the router (R1) becomes the WAN edge only. The access switch (ASW1) connects the users. R1's Loopback0 stands in for an Internet server (192.0.2.1).

What you’ll practise

  • Enable IP routing on a Layer 3 switch and create SVIs as VLAN gateways
  • Explain when an SVI is up or down (autostate)
  • Convert a switch port into a routed port
  • Route between a Layer 3 switch and a router with a default and a summary static route
  • Compare router-on-a-stick with Layer 3 switching and describe two-tier designs

The tasks

  1. Build the Layer 2 part
  2. Turn on routing and create the SVIs
  3. Make a routed port towards the router
  4. Route to the Internet and back
  5. Manage the access switch
  6. Compare the designs

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 CCNA 200-301 guided labs.

  3. Open 11 - Inter-VLAN routing on a Layer 3 switch - SVIs and routed ports 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.
