In this section, we explore the world of programming, algorithms, networks, and infrastructure
This hands-on lab configures static routes for IPv6 destinations between two routers, mirroring the IPv4 static routing syntax covered earlier in this series while highlighting the IPv6-specific command keyword and address format.
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.
