Packet Tracer - Amber light

[Armann]

Hey.

A beginner question here. Could someone explain to me why the amber light is on? Everything works but I haven't been able to figure it out and searching online hasn't helped yet. My guess is that it does it automatically so we don't have layer 2 loop in the network? Just wanted to ask since I'm new to packet tracer.

Thanks.

Hey, I can't delete my own question but I see now that it's STP and one is the root.
