Infrastructure, Systems, and Connectivity
This hands-on lab configures a default static route for IPv6 on an edge router, using the IPv6 equivalent of the all-zeros IPv4 default route to represent every otherwise-unmatched destination.
This hands-on lab configures a floating static route with a higher administrative distance than an existing OSPF-learned route, demonstrating how it remains inactive as a backup until the primary route fails, then automatically takes over.
This hands-on lab configures RIPv2 as a basic dynamic routing protocol between three routers, disables automatic summarization, and verifies routes are learned dynamically without any manual static route configuration.
This hands-on lab configures OSPF between two routers connected via a serial point-to-point link, verifies the neighbor adjacency forms quickly without DR/BDR election, and confirms routes are exchanged correctly.
This hands-on lab configures OSPF across an Ethernet segment with three routers, observing DR and BDR election in action and verifying how it differs fundamentally from the point-to-point behavior covered in the previous lab.
This hands-on lab manually sets a router's OSPF Router ID rather than relying on automatic selection from interface addresses, and verifies the change requires an OSPF process restart to take effect.
This hands-on lab configures a passive interface in OSPF so a LAN-facing interface still advertises its network while no longer sending or accepting OSPF hello packets on it, preventing unnecessary neighbor formation and unauthorized adjacencies on access-layer ports.
This hands-on lab uses debug ip ospf adj to observe the live OSPF neighbor formation process in real time, and deliberately introduces a hello/dead timer mismatch to show exactly how the debug output reveals the resulting adjacency failure.
This hands-on lab configures OSPF over a non-broadcast multi-access topology using manually specified neighbor statements, since this network type cannot rely on multicast hello packets to automatically discover neighbors.
This hands-on lab configures OSPF using the point-to-multipoint network type on a hub-and-spoke topology, comparing this approach against the manual neighbor statements required for non-broadcast networks in the previous lab.
This hands-on lab configures EIGRP between three routers using the network command, verifies neighbor relationships form, and confirms routes are exchanged, establishing the foundational EIGRP configuration workflow.
This hands-on lab configures EIGRP using precise wildcard masks in the network command to advertise only specific subnets rather than entire classful networks, giving finer control over exactly which interfaces participate in EIGRP.
