The Spanning Tree Protocol (STP) is a protocol used to prevent loops in a network topology. To do this, STP elects a root bridge, which serves as the focal point of the network, and all other bridges in the network connect to it.
The two values used by Spanning Tree Protocol to elect a root bridge are:
Bridge Priority: Each bridge in the network has a configurable priority value, with the default value being 32768. The bridge with the lowest priority value becomes the root bridge. If there is a tie, the bridge with the lowest MAC address is selected as the root bridge.
MAC Address: If two bridges have the same priority value, then the bridge with the lower MAC address is elected as the root bridge.
In summary, the two values used by Spanning Tree Protocol to elect a root bridge are the Bridge Priority and the MAC Address. The other options listed in the question, such as amount of RAM, IOS version, IP address, and speed of the links, are not used in this process.
