Re: Spanning tree root and network traffic question

No, it does not imply that all traffic will traverse the root.

If your new root has only one link, no traffic will traverse it.
But it will get involved in all TCs (topology changes).

If it does have more than one link, then things get more weird,
as both links will be in your ST and at most half of your traffic
will go through it (for as long as it lives :)
