How Does MSTP Operate in the Network?

In the following diagram of a small 802.1d bridged network, STP is necessary
to create an environment with full connectivity and without loops.

Switch B
VLAN 20
Assume that Switch A is elected to be the Root Bridge, and Port 1 on Switch
B and Switch C are calculated to be the root ports for those bridges, Port 2 on
Switch B and Switch C would be placed into the Blocking state. This creates a
loop-free topology. End stations in VLAN 10 can talk to other devices in
VLAN 10, and end stations in VLAN 20 have a single path to communicate
with other VLAN 20 devices.
