10 hands-on Addressing scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Focused Addressing configuration and troubleshooting practice for CCNA and CCNP.
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.
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.
Configure and verify dual-stack IPv4 and IPv6 addressing on Cisco IOS router interfaces. R1-R2 share a /30 IPv4 and /64 IPv6 point-to-point transit, while R1 provides a dual-stack user LAN gateway. No routing protocols or router static routes are permitted; verify only directly connected reachability.
Configure IPv6 global unicast on a router-to-router link using EUI-64-derived interface IDs. Enable IPv6 unicast routing, set explicit link-local addresses, and verify that each router auto-forms its 64-bit interface ID from the MAC (FFFE insertion with U/L bit flip). Validate directly-connected reachability only. No routing protocols or static routes.
Advanced IPv6 interface addressing on Cisco IOS routers. Configure explicit, predictable IPv6 link-local addresses alongside global unicast addresses on a point-to-point router-to-router link. Validate with show commands and neighbor pings using the link-local as the destination, and confirm host-to-gateway reachability on local LANs. No routing protocols or static routes are used; focus is strictly on interface IPv6 addressing mechanics.
Enable IPv6 forwarding and configure IPv6 global unicast addresses on directly connected links only. No routing protocols or static routes. Verify that each device can reach only its directly connected neighbors using IPv6.
Configure an IOS-XE router as a DHCP server with a correctly scoped pool and an excluded-address range that protects the gateway and a reserved static server (.10). Two Alpine clients obtain addresses dynamically from the remaining range (starting at .11). Verify leases, confirm the excluded count, and ensure the reserved static never appears as a DHCP binding.
Configure an IOS router as a DHCP server and have another IOS router obtain its uplink address dynamically via DHCP on a shared LAN. Validate the lease from both the client and server perspectives and test reachability from attached hosts.
Build and verify two independent DHCP address pools on a single Cisco IOS router, each serving a different LAN. Two Alpine Linux clients obtain leases from their respective pools via directly attached access switches. You will configure the pools, excluded addresses, default gateways, DNS, and domain names, then verify with IOS show commands and Linux tools. The focus is deterministic router DHCP configuration; clients lease dynamically and are verified rather than graded.
Beginner CCNA lab focusing on IPv4 addressing and basic Layer 3 verification on a small branch network. You will assign IP addresses to router interfaces, confirm end-host default gateways, and verify connected reachability using host-based pings. You will also learn to read 'show ip interface brief' and 'show ip route' to confirm operational state before any routing beyond directly-connected networks is configured.
