WebSep 28, 2011 · The STP algorithm is responsible for identifying active redundant links in the network and blocking one of these links, thus preventing possible network loops. The operation of STP is as follows: STP enabled switches exchange BPDU messages between them to agree upon the "root bridge;" the process is called Root Bridge Election. WebSW1 has won the election process and is the root switch. Consider the SW3’s perspective for choosing its root port. Two paths are available to reach the root switch, one direct path over Fa0/1 and the other going out Fa0/2 and through SW2. The direct path has a cost of 19, while the indirect path has the cost of 38 (19+19). ethical challenges in information technology
