Spanning Tree's job is to eliminate multiple paths to a single destination.
If it finds more than one path it will put one of them into blocking mode to
ensure a loop free path. Remember, Spanning Tree runs at layer two and has
no concept bandwidth. If you need to setup equal cost paths to a certain
destination, you will need to do it at layers above layer two.
Pick up a copy of Radia Perlmans 'Interconnections' second edition. Radia
is the primary authority on the Spanning Tree algorithm, she will enlighten
you. This is also good solid study for deeper networking knowledge.
