stp or dynamic stp?

[langog]

the stp construct a static topology.

can anybody tell me some tech about

dynamic method which according user

application demands?

i know,this question is a bud in my

head.and,this quesiton perharps is no

a question.

May I know what is the exact requirement of this dynamic stp in your network environment? Because, stp can't be considered to be statically built.If we take in the other way, if one of the forwarding port of a stp tree is "down". the stp dynamically changes the blocked one to forwarding one.Also, ifone of the switch involved with this spanning tree is down, the stp dynamically conducts reelection and elects the new root and builts a new spanning tree.

Hence, it is aqlso dynamically built.

I mean,if the net topology is stable.But user want to sort applications by select different switches for stp's root .what tech can u use?
