First, the preparation of knowledge???????? The routing algorithm of link State Route is a global route-selection algorithm. In this algorithm, we assume that all network topologies and link charges are known (in practice, by having each node broadcast link-state groupings to all other nodes in the network), the "OSPF protocol" enables all nodes to have a complete view of the network equivalent through node broadcasts. After the view is obtained, the LS
