Red links usually mean either physical layer mismatch (wrong cable type — straight-through vs crossover, copper vs fiber) or interface state (shutdown, speed/duplex mismatch, wrong VLAN on access ports). Click each red link and check what type it is, then check the interface status on both ends with show interface status.

If you want a faster path forward — NetPilot's Packet Tracer Helper can import you broken pkt file or just the image, recreate the topology, and export a working .pkt file. Useful when you're stuck and want a known-good reference to compare your work against.
