In the STP circuit like bellow, will the Router2 select a root port? or just the Router1 and Router3 select root port?
in a tutorial it says "all the non-root bridge node will select a root-port, its principle is 'towards'(near) the root-bridge".
my understand is the Router2 is also the non-root bridge node. if it will choose a root port, its
G0/1 all are 'towards' to the root bridge. then how to choose ?
