MikroTik MTCNA lab 8 of 19

Static routing

Connect three sites with static routes: read the RouterOS 7 routing table and its flags, add routes to remote networks, use a default route with a more specific exception, and add a backup route with a higher distance, then find out why a backup must work in both directions.

Run this lab

It needs Lite: its 6 nodes are set to 6 vCPU and 3,840 MB in total. That fits the free demo too.

In your workspace: Shared, then MikroTik MTCNA RouterOS v7 guided labs, then 08 - Static routing

The scenario

A garden-centre chain has three sites joined by private links in a triangle: head office (R1), the depot (R2) and a shop (R3). Every router knows only its own networks, so nothing works between sites. There is no routing protocol budget this year, so you will use static routes, and make sure that losing the HQ–depot link doesn't stop the depot.

Routerether1ether2ether3 (LAN)
R1 (HQ)10.0.12.1/30 → R210.0.13.1/30 → R3192.168.1.1/24, PC1 .10
R2 (Depot)10.0.12.2/30 → R110.0.23.1/30 → R3192.168.2.1/24, PC2 .10
R3 (Shop)10.0.23.2/30 → R210.0.13.2/30 → R1192.168.3.1/24, PC3 .10

What you’ll practise

  • Read /ip route print and explain the flags D, A, c, s, d and the distance column
  • Add static routes with a gateway, a comment and a distance
  • Explain longest-prefix matching with a default route plus a more specific route
  • Build a floating backup route and test it by failing a link
  • Explain why return traffic needs its own route, and use check-gateway

The tasks

  1. Read the routing table
  2. Add routes to the other sites
  3. A default route with one exception on the shop router
  4. Add a backup path for the depot
  5. Fail the HQ–depot link, and fix the return path

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 MikroTik MTCNA RouterOS v7 guided labs.

  3. Open 08 - Static routing 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.
