History and motivation. It was originally defined in IEEE 802.1s as an amendment to 802.1Q, 1998 edition and later merged into IEEE 802.1Q-2005 Standard, clearly defines an extension or an evolution of Radia Perlman’s Spanning Tree Protocol (STP) and the Rapid Spanning Tree Protocol (RSTP).
Spanning tree protocol selects one switch as the root switch for every switched LAN. This root switch is This root switch is used as the reference point to decide the spanning tree topology.

Spanning Tree Protocol (STP) was developed to prevent the broadcast storms caused by switching loops. STP was originally defined in IEEE 802.1D.
Before we talk about Spanning Tree Protocol, For example, if the CBPDU comes in Fa0/1, the switch will ad 19 to 0 (if you look at the Port Costs table you can see that the cost for a 100Mbps link is 19) so, 19 + 0=19. So this switch will forward a copy of the CBPDU received advertising a Cost to RB value of 19. The next switch will receive this BPDU and again add the cost value of the port
