CCNP Route Control: A Second Boundary and the Distance Trap
Today's daily lab
Add a second boundary router for resilience, then stop it from routing the acquired site's routes the long way round.
Learning objectives
- Add a second redistribution point between OSPF and EIGRP
- Spot a boundary that prefers the long path to an external route
- Fix it by changing administrative distance on both boundaries
Troubleshooting focus
- A boundary reaches 10.41.1.0/24 through HQ: compare the distances of its two routes
- Only one boundary takes the long path: it heard the other's OSPF copy first

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.
