I have a question on Spanning tree across the core layer. If I have
switch
stacks that look like the following diagram: 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 2924 5000 5000 5000 5000 5000 5000 5000 5000 5000 6500a 6500b If I have two links going to each 6500 from the 5000s and the 6500a switch is the root bridge, then is 6500b switch even going to be used. From my understanding of STP, all traffic is going to go through the root bridge in the even of redundant paths. If this is true then (not that I am downing fault tolerance) it is a waste of a switch that costs thousands of dollars just to sit there and wait for the 6500a switch to go down. Am I getting this correct or is there a way to setup STP so both 6500s get used with about the same load? |
