RE: BPDU & Root Guard

root guard should be applied to the edge of your controlled network. So not
only the root switch but all your downstream switches too. You wouldn't
want half of your network to disagree on who is root.

Hi Tony,

Root guard is ideally applied on all the ports of a root bridge so that it
will not allow any superior BPDU's to demote itself.
