If a node’s distance for a path2 to the root (a bridge’s priority vector) decreases (gets better) that node has to either (a) delay sending agreements with the new distance or (b) stop forwarding frames on that path, until (c) the agreement messages from the node’s neighbours signal their awareness of the new distance. On the other hand if a node’s distance gets worse, the node can begin or continue forwarding from (and/or to, as specified by the particular rule) any given neighbour—up to the point where that neighbour is forwarding to the node in the belief that the node is closer to the root but that is no longer guaranteed. Figure 1 shows a fragment of a network using spanning tree forwarding (bridges A,
