However with per vlan spanning tree, vlans 100 and 300 in this example, their running two different instances of spanning tree protocol, but we can do instead, if we do have lots of vlan, we could define different spanning tree instances, we might say here is an instance where which switch a is the root, here is an instance where switch b is the roo t, and then we could. Using their spanning tree protocol emulation software all the spanning tree. To go beyond stp requires a user level daemon that will manage the tree topology and changes to that topology.
