Spanning tree bridge priority values

WebA spanning tree is a sub-graph of an undirected connected graph, which includes all the vertices of the graph with a minimum possible number of edges. If a vertex is missed, … WebThe Spanning Tree Algorithm in use by 802.1d (STP), 802.1w (RSTP), and 802.1s (MST) states that the bridge (switch) with the lowest bridge ID (BID) will become the root bridge. The bridge ID is composed of a 2 byte priority value followed by a 6 byte MAC address (usually a burned in address [BIA] on the switch).
