Spanning tree protocol is a network protocol that is used to ensure a loop-free topology. The basic function of the STP is to select which port will be use if there are occurs in redundant link which act as backup if the active link fails.The inventor of the STP is called Radia Perman, which is a software designer and network engineer, How the STP works? Root Bridge(bridge and switch is same thing) --> switch with the lowest mac address become root bridge,if and only if the priority is same Elect Root Port (RP) --> root port is port on the non root bridge pointing back to root bridge depend on speed (higher speed == lower cost) and port id (lowest port id win) Elect Designated Port (DP) --> port at root bridge pointing toward non root bridge Elect Non-designated Port (NDP) --> port on non-root bridge pointing towards root bridge that is block automatic become standard port The switch will sent Bridge Protocol Data Units (BPDU) to nearby switch (default sent every...
