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.
