Document Content and Description Below

Networking Notes2.docx Networking General Spanning-Tree Spanning-Tree Protocol is a link management protocol that provides path redundancy while preventing undesirable loops in the network. For an ... Ethernet network to function properly, only one active path can exist between two stations. Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the potential exists for duplication of messages. When loops occur, some switches see stations appear on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.
