Static Route: Wrong Next Hop

R1's static route to a remote LAN never shows up in the routing table. Find out why, repair it, and prove the remote LAN is reachable.

What you'll practise

  • Read a prefix-specific route lookup
  • Distinguish a destination network from its next hop
  • Replace an invalid static route safely
  • Verify both the routing table and end-to-end reachability

Set it up

  1. 1

    Have the node image ready

    Images are not included. The file expects your own licensed copy of:

    • iosv-159-3-m6

    If your copy has a different name, open each node's Edit dialog after importing and pick your image from the list.

  2. 2

    Copy it to the server and fix permissions

    Replace <your-server> with the IP address or hostname of your EVE-NG or PNETLab server.

    $ scp static-route-wrong-next-hop-lab.unl root@<your-server>:/opt/unetlab/labs/
    # then, logged in to the server:
    $ /opt/unetlab/wrappers/unl_wrapper -a fixpermissions
  3. 3

    Open it and start the nodes

    The canvas notes list the objectives, and the workbook walks through the fix.
