MSTP enhancements
Although RSTP resolved most of STP’s limitations, it did not make the protocol VLAN
aware. MSTP was designed to provide this capability while still delivering fast
convergence if a switch, port, or link fails.
MSTP supports multiple STP instances on the same network, and each instance can
include one or more VLANs. When a port belongs to multiple VLANs, it may be
blocked in one instance, but forwarded in another. This provides multiple preferred
paths for data traffic and achieves load-balancing across the network.
In this example network, MSTP has been configured to support two groups of VLANs.
