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.
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.
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.
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.
