CCNA L3 Switching: A Routed Uplink to the Edge
Today's daily lab
Lab 2 of 2 in CCNA Layer 3 Switching: Route on the Switch · ← Previous
CCNA exam domain: IP Connectivity
Connect the campus to the edge router over a routed link, and give traffic a way out and back.
Learning objectives
- Convert a switch port into a Layer 3 port
- Route campus traffic to the edge and back with static routes
- Verify host reachability to the edge services address
Troubleshooting focus
- The uplink refuses an address: the port is still switching
- Pings leave the campus but never return: the far router has no route back

How this lab is graded
- Build it your way. Where a lab lets you choose a value — a VLAN name, an interface description — grading checks that you configured it, not which name you picked. Names that another line has to reference, like an ACL applied with
access-class, are stated in the guide and do have to match. - Addresses, modes and protocol keywords are exact. An IP address, a subnet mask,
switchport mode trunk, an encapsulation — these carry the meaning of the lab, so they are graded as written in the guide. - Grading reads your saved configuration. Export the lab from CML after you have configured it, and make sure anything you set is in the
running-config— a change that only exists in a terminal session never reaches the grader. - You can submit as many times as you like. Your best score stands, and each attempt tells you which checks passed so you can work the gaps.
- Scored something you believe is correct? Use Report an issue on this page — that is exactly how the grading fixes in the changelog got found.
