7.5 STP (Spanning Tree Protocol)
Spanning tree is a link management protocol that provides path redundancy while preventing undesirable loops in
the network. For Layer 2 Ethernet network to function properly, only one active path must exist between two
stations.
The spanning-tree algorithm calculates the best loop-free path throughout a switched network. STP forces
redundant data paths into a standby (blocked) state. If a network segment in the spanning tree fails and a redundant
path exists, the spanning-tree algorithm recalculates the spanning tree topology and activates the standby path.
