Design and implement a 3-router full-mesh with two edge LANs using static IPv4 routes only. Edges use primary defaults toward the core plus floating (higher AD) backup defaults; the core uses specific routes for the edge LANs. Validate bidirectional reachability, path choice, and failover behaviors from real hosts.
Hands-on IPv6 static and default routing across a 3-router, 2-LAN topology with end-user hosts. You will enable IPv6 unicast routing, apply IPv6 addressing, configure hub-and-spoke static and default routes, and validate bidirectional host reachability. The guide provides scenario context, step-by-step tasks with the why behind each action, and targeted troubleshooting.
Implement VLANs, 802.1Q trunking, router-on-a-stick inter-VLAN routing, and access-layer port security on a compact branch network with two access switches and two endpoints. You will configure segmentation (VLANs 10, 20, 99), hardened trunks with a dedicated native VLAN 999, Layer 3 gateways on a core router, and sticky MAC port security on user-facing ports. Verify end-to-end reachability and remediate common misconfigurations like missing allowed VLANs, native VLAN mismatches, and unauthorized endpoint moves.
Build a 3-router triangle with two end-to-end paths between Branch A and the Data Center. Stand up OSPF area 0, create an ECMP condition, then intentionally steer traffic using ip ospf cost. Verify from the end hosts and troubleshoot common OSPF control-plane mismatches.
Deploy a compact enterprise multi-area OSPF with a backbone (area 0) and one branch area (area 10). You will configure area 10 as a stub, then transition it to a totally-stubby area from the ABR, validate reduced LSDB and routing tables, and simulate an operational fault (area mismatch) to diagnose adjacency loss and restore full transit. The lab uses three routers and two hosts to verify end-to-end reachability and real-world outcomes.
Build a 5-node CML lab to design OSPFv2 across two areas with an ABR that summarizes non-backbone routes using area range. Validate adjacencies, end-to-end reachability, and that the backbone learns a single summary in place of specific inter-area routes. Intentionally introduce an area mismatch, diagnose why the adjacency does not form, and repair it.
Deploy OSPFv2 with MD5 authentication on backbone links, deliberately trigger and diagnose an area mismatch adjacency failure, then fix it and restore end-to-end reachability between two branch hosts in a compact three-router topology.
Build and troubleshoot a compact multi-area OSPF design with a single ABR between area 0 and area 10. You will deploy OSPF, observe an adjacency failure caused by an area mismatch on one transit link, repair it, and validate that routes propagate end to end between two user LANs.
Hands-on CCNA Layer 2 switching lab: build VLANs, access ports, hardened 802.1Q trunks, and basic port-security across two access switches and an L2 core. Verify segmentation end-to-end from real hosts and practice troubleshooting native-VLAN and port/VLAN mismatches.
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.
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 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.
