First steps: your first fix in the lab

Welcome to the lab

This is a quick tour. You'll fix one thing, watch the network react, and earn your first verified proof, all in your browser, nothing to install.

The setup

Two routers, r1 and r2, are connected on 10.0.0.0/30. r2 has a loopback address 2.2.2.2. Right now r1 can't reach 2.2.2.2: it has no route to it.

Your job

Give r1 a static route to 2.2.2.2 so it can reach r2's loopback.

Step by step

1. The diagram at the top is the network. Click r1 to open its terminal.
2. Run show ip route and notice there's no entry for 2.2.2.2.
3. Try ping 2.2.2.2. It fails because r1 doesn't know the way there.
4. Add the route:

   enable
   configure terminal
   ip route 2.2.2.2 255.255.255.255 10.0.0.2
   end
   

5. Run ping 2.2.2.2 again. It works now.
6. Watch the Objectives panel turn green as you go, then hit Check solution to claim your proof.

Stuck? Use the Hint button. Want a clean slate? Reset to starter puts everything back.

That's the whole loop: read the network, make a change, verify it, get graded. Every challenge works the same way.
