CCNA OSPF Day 7: Passive Interfaces + Default Origination
Deploy OSPFv2 across a small branch-to-edge topology, mark user-LAN interfaces passive, and originate a default route at the edge so branch hosts learn O*E2 and can reach an internet-facing host. You will implement, verify, and troubleshoot OSPF passive interfaces and default-information originate.

CCNA EIGRP: Passive Interfaces
Build and verify EIGRP on a small routed topology while marking the user-facing LAN interface as passive. You will advertise the LAN into EIGRP without forming an adjacency on that segment, preventing rogue neighbors and reducing control-plane noise. Focus on deterministic EIGRP configuration, wildcard-based network inclusion, and verification using show commands.

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.
