High-availability and increased capacity
With MSTP, a link can be active for instance, but blocked for another instance. On
this network, for example, the links between switches A and C and A and D are
blocked for instance 1 but active for instance 2. The ports for these links will have a
different state for each instance.
The graphic below shows the dual states of the port on switch C.
MSTP can improve network utilization and capacity because ports have less idle
time.
