Re: SPT guard root and guard loop.

Sure, designated ports are the ones closer to root, right ?
Standing in the medium, i.e., outside any switch.

The point here is that STP changes dinamically port roles.
And loop guard/root guard are static policies that prevent
STP from reaching an "ilegal" state.
As they are complementary of one another, they make no sense
applied at once.
