WebOct 4, 2016 · Letting the network pick your root bridge. As the name suggests, spanning tree resolves loops in your network by creating a logical tree structure between the switches. One switch becomes the root of the tree, and is called the root bridge. All other switches then figure out the best path to get to the root bridge. WebMar 23, 2024 · An edge port connects to an end station and assumes that the switch port does not connect to another switch. RSTP edge ports should immediately transition to the forwarding state, thereby skipping the time-consuming 802.1D listening and learning port states.

Spanning trees are special subgraphs of a graph that have several important properties. First, if T is a spanning tree of graph G, then T must span G, meaning T must contain every vertex in G.
