CCNP Route Control: Fail Over When the Provider Goes Quiet
Today's daily lab
Lab 8 of 8 in CCNP Route Control: Redistribution, Route Maps, PBR & IP SLA · ← Previous
The primary provider can fail without the link going down, and the default route never notices. Probe it, track it, and fail over to the backup.
Learning objectives
- Probe the primary provider with an IP SLA operation
- Tie the primary default route to a track object
- Fail over to a floating backup route and back again
Troubleshooting focus
- The backup route never installs: compare its distance with the primary's
- The track never goes down: check what the probe is aimed at and where it is sourced

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.
