RSTP and loop prevention

Read the explanation, try the exercise, then answer the quiz.

Understand the concept

Ethernet switching loops can cause broadcasts to circulate indefinitely. Spanning Tree Protocol blocks redundant paths while maintaining a loop-free logical topology.

Rapid STP (802.1w) uses root, designated, alternate, and backup port roles. It converges more quickly than traditional STP in common topologies.

TRY IT YOURSELF

Practice task

On a diagram with redundant switches, select the root bridge, then label the expected forwarding and alternate paths.
