5 hands-on Subnetting scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Focused Subnetting configuration and troubleshooting practice for CCNA and CCNP.
Practice deterministic VLSM planning and interface addressing on two Cisco IOS routers. Starting from a single /24, allocate three right-sized IPv4 subnets (two LANs represented by loopbacks and one router-to-router WAN) and configure exact interface addresses and masks. No routing protocols or static routes are configured; verification focuses on directly connected reachability and show commands.
Advanced CCNP lab focused on diagnosing and correcting IPv4 interface addressing issues on Cisco IOS routers. The lab ships pre-broken with two independently failing faults that the learner must find and fix using show commands and directed pings. No routing protocols or static routes are used — verification is limited to directly-connected neighbor and gateway reachability.
Build confidence addressing IPv4 point-to-point WAN links on Cisco IOS using /30 and /31 masks. Two routers are connected by two parallel links: one classic /30 and one RFC 3021 /31. No routing protocols or static routes are configured — the goal is deterministic, correct interface addressing and verification of directly connected reachability. A small LAN off R1 with two hosts allows additional verification (host-to-gateway only).
Beginner CCNA lab (1 of 10) focused on configuring and verifying IPv4 interface addressing on Cisco IOS routers. Learners assign given /24 addresses to two router interfaces and validate directly-connected reachability. No routing protocols or static routes are configured in this lab.
Hands-on IPv4 subnetting and interface addressing on three IOS routers and one client. You will split a /24 into four equal /26s, assign the correct /26 mask to each link, and configure deterministic lowest-usable addressing on router interfaces. No routing protocols or static routes are used; verification is strictly directly-connected reachability.
