Spanning tree Priority

[lcarbajalparedes]

Hello,

Recently we will add 2 new core Switch 3750X, these 2 equipments will manage the spanning tree ( root)

my idea is to change the priority in order to make 1 or the 2 of them the root, my question is  if i setup the same priority for both when one go down the other will assume the role of root in the spanning tree topology ?

About the using L2 or L3 unfortunately i think that series (HP) only support L2  not L3, thats why i was looking options for the spanning tree.
