Explanation:
Multiple Spanning Tree Protocol (MSTP) was first specified in IEEE 802.1s and is standardized in
IEEE 802.1Q. MSTP enables multiple VLANs to be mapped to the same spanning-tree instance,
reducing the number of spanning-tree instances needed to support a large number of VLANs.
MSTP provides multiple forwarding paths for data traffic and enables load balancing. It improves
the fault tolerance of the network because a failure in one instance, or forwarding path, does not
affect other instances
