RE: Spanning-tree Guard Root

My understanding of root guard was to ensure the path to the root was not possible through any ports with root guard enabled on them.

IE I've setup my infrastructure so that the shortest path to root is through 1 of 2 of my ports on my switch one showing that it is blocked while the other is forwarding. You would enable root guard on all other ports to make sure that they would shut down if for some reason they became the best path to the root.

That's my understanding too. To prevent another switch with a lower
priority from becoming the root bridge.

Any other explanation Experts?

Thanks,
