z IEEE 802.1s: Virtual Bridged Local Area Networks—Amendment 3: Multiple Spanning Trees
MSTP Configuration Task List
Before configuring MSTP, you need to know the role of each device in each MSTI: root bridge or leave
node. In each MSTI, one, and only one device acts as the root bridge, while all others as leaf nodes.
Complete these tasks to configure MSTP:
