Spanning-tree uses cost to determine the shortest path to the root bridge. The slower the interface, the higher the cost is. The path with the lowest cost will be used to reach the root bridge. Here’s where you can find the cost value: In the BPDU, you can see a field called root path cost. This is where each switch will insert the cost of ...We start from the edges with the lowest weight and keep adding edges until we reach our goal. The steps for implementing Kruskal's algorithm are as follows: Sort all the edges from low weight to high. Take the edge with the lowest weight and add it to the spanning tree. If adding the edge created a cycle, then reject this edge.5 may 2023 ... Bal introduced me to graph theory, mathematics research, and the game of Set, all of which I am very grateful for. Additionally, I want to thank ...Spanning trees A spanning tree of an undirected graph is a subgraph that’s a tree and includes all vertices.
