2 hands-on Interface Addressing scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Interface Addressing configuration and troubleshooting practice for CCNA and CCNP.
Included with a subscription
Configure a Cisco IOS router to host two IPv4 /24 subnets on a single physical LAN interface using a secondary address. Verify directly-connected reachability only (no routing protocols, no static routes). This simulates a readdressing coexistence period where both old and new subnets must operate concurrently on the same segment.
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.
