CCNA: OSPF Passive Interfaces & Default Origination

Deploy OSPFv2 across a 3-router, 2-LAN branch/core/edge topology. Mark LAN-facing interfaces as passive so they do not send OSPF hellos or form adjacencies. Originate a default route only from the edge router and verify default propagation end-to-end using real client traffic. Includes realistic troubleshooting around missing adjacencies, non-propagating defaults, and unreachable external destinations.

OSPFv2: Router IDs, Neighbor States, and Loopback Adjacency

Deploy OSPFv2 across three routers with unique, loopback-derived router-ids. Observe OSPF neighbor state transitions, advertise loopbacks and LANs, and troubleshoot an adjacency failure caused by a duplicate router-id. Validate full end-to-end reachability from client hosts after fixing the issue.

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

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.

OSPFv2 Single-Area Fundamentals: Adjacency and Area 0 Basics

Hands-on CCNA beginner lab: build a 3-router chain with end hosts, enable OSPFv2 area 0, form full adjacencies, advertise loopbacks and LANs, verify route propagation end-to-end, and intentionally create then resolve an OSPF area mismatch on a transit segment.

VLANs for Two Departments: Trunking & Sticky MAC Security

Hands-on CCNA lab: build VLANs for Sales and Engineering, implement 802.1Q trunks with a hardened native VLAN, assign access ports, and apply sticky MAC port-security on access interfaces. The design uses a compact, realistic branch topology with a router-on-a-stick gateway, a distribution L2 switch, one access L2 switch, and two end hosts. Students deploy, verify, and troubleshoot VLAN reachability, trunk integrity, and port-security violations.

Compact Branch LAN: Two VLANs, ROAS & Sticky Port Security

Configure a compact branch LAN with router-on-a-stick inter-VLAN routing, two access switches, and two user VLANs. Implement VLANs, 802.1Q trunks with a hardened native VLAN, secure user-facing ports with port-security, and verify end-to-end reachability from the hosts. Includes realistic troubleshooting of VLAN assignment, trunk allow-lists, and port-security violations.

Campus Layer 2: VLANs, a Management VLAN & Port Security

Build and harden a small branch campus Layer 2 network with a distribution switch and two access switches. Implement VLANs, trunking, and basic port security, then verify from the end hosts and troubleshoot common L2 mistakes.
