WebIf we enable portfast while running the classic spanning tree it will skip the listening and learning state and put the interface in forwarding state right away. Besides moving the interface to the forwarding state it will also not generate topology changes when the interface goes up or down. WebMathematical Properties of Spanning Tree. Spanning tree has n-1 edges, where n is the number of nodes (vertices). From a complete graph, by removing maximum e - n + 1 edges, we can construct a spanning tree. A complete graph can have maximum nn-2 number of spanning trees. Thus, we can conclude that spanning trees are a subset of connected …
