MST incorporates a compatibility mechanism which make an MST Region appear like what to external switches?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
MST uses a Special STP Instance, which is always the first instance, Instance 0. What is the name of this MST Instance?
MST, using the IST instance of STP, only advertises one set of BPDUs, minimizing STP Traffic, while still providing all information for all MST Instances. Which 2 properties make this possible?
