CCNP VRF & GRE: A Routing Process per Tenant
Today's daily lab
Lab 3 of 3 in CCNP Virtualization: VRF-Lite & GRE · ← Previous
Static routes don't scale. Give each tenant its own OSPF process, so its routes are learned instead of typed.
Learning objectives
- Run a separate OSPF process inside each tenant's routing table
- Keep each tenant's adjacency and routes apart from the other's
- Verify each tenant learns its services route from OSPF
Troubleshooting focus
- A tenant has no neighbor: compare the tenant, area and subnet on both ends
- A neighbor shows an unexpected router ID: set each process's ID explicitly

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.
