    STP Cost Paths Question

    Hi everybody,

    I am just an IT student and i am actually learning about STP protocol. At school they told us one thing that seems weird to me :

    I precise that we decided to not consider the priority field (priority number + vlan id) in the Bridge ID section so that the Bridge ID is only composed of the Mac @ of the bridge.

    When you have a bridge that is not directly connected to the root bridge but offers two paths that have the same cost to reach the root bridge, the bridge will select what ? the lowest path I guess (Lowest BID) but the teacher told us that only the root bridge election process used the lowest BID and that for the selection of one path between two paths with the same costs we must consider the highest BID (seems weird no ? Coz' with Cisco I learned that Lowest is best ....)

    Thus i have an exam in 4 days and that i tried to join my teacher without success, i am asking the community.

    Thanks to everybody that reads this post and therefore responds.
