WebWe 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. Web7. sep 2009 · There is one additional caveat to PVST+, is by default, the path cost assigned by PVST+ is based on Cisco's STP cost convention, not the IEEE STP cost. Therefore, the path cost needs to be changed so that it complies with IEEE STP path cost and all similar links (like FastE, GbE) have the same link-cost value.
