Spanning Tree Protocol (STP) is a link management
protocol that helps to
prevent undesirable loops occurs in the network. For an Ethernet network to
function properly, only one active path can exist between two stations. If a
loop exists in the network topology, duplication of messages will occur and this
might confuse the forwarding algorithm and allow duplicate frames to be
forwarded.
