MSTP
Depend on VLAN configuration, there may not be any loops even if it looks no-loop in physical network. In that
case, STP decides it as loop network, but MSTP does not because it can handle the network per VLAN. Therefore,
MSTP can forward network data more efficiently than STP.
For example, There are 4 switches called Bridge A, Bridge B, Bridge C, and Bridge D and connect them as below
diagram. topology. Using MSTP, we can forwards vlan 100, 200 frame from Bridge D – Bridge B – Bridge A and
forwards vlan 300 frame from Bridge D – Bridge C – Bridge A. We can not use STP for such behavior.
