Secondary IP on a LAN Interface

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.
