STP prevents Layer 2 loops from forming in switched networks with redundant paths by dynamically blocking ports on switches. It elects a root bridge and calculates the shortest path from each switch to that root, blocking ports along redundant paths. If a failure occurs, STP will unblock previously blocked ports to allow traffic to flow over the new optimal path. This maintains a loop-free topology while leveraging backup links for redundancy and fault tolerance.
