54. Spanning Tree Protocol (STP) commands
526

MSTP
MSTP (Multiple Spanning Tree Protocol) is also a modified STP protocol to
communicate data for each VLAN using different routes. This allows for effective use
of bandwidth.
Consolidating multiple VLANS into a group called instance can reduce more CPU
loads compared to when designing a spanning tree instance for each VLAN.
The MSTP function allows for supporting a large-size network.
