Ron : I am not running MST on the Cisco access layer. This was not my design - it is indeed a really bad decision made 10 years ago. The easiest way would be to just run MST on all switches, but that can't be done right now. – Jeremy G. Dec 15 '15 at 18:09 Well, as you said, revision number has to match in a MST domain. Yes, while you dont configure both switches in the same name,instance map and revision they belong to different MST domains. In a production environment, you have to change it in a maintenance window , when you are allowed to do such changes, Cheers
IEEE 802.1s is based on the Cisco Multiple Instance Spanning-Tree Protocol (MISTP) which is often simply referred to as Multiple Spanning Tree (MST). The Cisco implementation is often referred to as Multiple Spanning Tree (MST). MSTP maps multiple VLANs into the same spanning-tree instance. It supports up to 16 instances of RSTP.
Multiple Spanning Tree (MST) By default Cisco Catalyst Switches run PVST+ or Rapid PVST+ (Per VLAN Spanning Tree). This means that each VLAN is mapped to a single spanning tree instance.
