I need an answer to this puzzling scenerio i have been asked to work with.I have two vlans with about 10 switches on each end and there is a link switch that has a connection to both sides of the VLAN. I have been asked to create a singular spanning tree for the entire scenerio. how can i go about this.

please i am awaiting the opinions of anyone knowledgable in this line. thanks.

Hi, I agree you can config MST on your router to reduce the number of spanning tree instances runing on the switch from one per vlan. You will have to map your vlan range to the MST, useful CLI commands are

spanning-tree mode mst

spanning-tree mst configuration

name (name)

revision( revision number)

instance (number) vlan (vlan range)

check your config using

show spanning-tree mst configuration.

Hope thsi will hlep you get started.
