Maximum MST instances
Hi folks,
I have read different numbers for the maximum number of MST instances:
- "Cisco supports a maximum of 16 MSTI's in each region" - OCG page 279
- "But each region can only support up to 64 spanning tree instances" - Cisco configuration guide - Configuring MSTP, page 16
Are these two conflicting, or is there something about MST and RSTP going on here that I am unaware of?

Got the answer (kind of) from Cisco discussions:
It's vendor and implementation dependant.
As an example, Nexus 3000 with NX-OS 7 supports up to 65 MST instances.....2017 Goals: Cisco: [x]Switch [ ]Route [ ]Tshoot
