Redundant Links
Rev. 9.41 Module 5 – 127
STP overview
Spanning-Tree Protocol (STP) is an industry-standard link management protocol that
supports path redundancy while preventing undesirable network loops. STP
automatically detects redundant links, calculates the lowest cost path (or preferred
path) through the network, and then blocks all other redundant links.
If a link in the preferred network path fails, STP changes the state of a blocked link to
enable a new path.
