OSPFv2 Multi-Area Capstone: 3-Rtr Line, Auth, LAN Host Intact

Bundle lab · $29.99

Advanced CCNP OSPFv2 multi-area capstone. Build a three-router line topology with area 10 at the branch, area 0 at the core, and MD5 authentication on the area 0 transit. Advertise all loopbacks and a branch user LAN. Validate end-to-end reachability from the branch host to every router loopback and the core LAN. Includes realistic enterprise management and verification flows.

Learning objectives

• Design and configure multi-area OSPFv2 over a realistic branch-to-core topology with an ABR.
• Implement and verify OSPF MD5 authentication on area 0 transit links.
• Advertise router loopbacks and a branch LAN while keeping user-facing interfaces passive.
• Verify inter-area route exchange from end hosts and troubleshoot common adjacency and reachability issues.

Troubleshooting focus

• Verify every link's interface status and IP addressing (`show ip interface brief`) and correct any interface that is down or misaddressed.
• Confirm each device's running configuration matches the lab objective, and bring any interface, route, or service that is not in its expected state back to health.
• Trace end-to-end reachability with ping/traceroute and isolate the first hop where forwarding fails.
