In the figure above Q3, if the routers agree to use the OSPF protocol (a link state method) to build their routing tables. Routers start flooding LSAs which to help each other in building a complete graph structure for the network. At one time during the flooding, router E has thefollowing information in its LSDB: If router E got the following LSA from router F, answer the following: A - How would the LSDB of router E looks like after completing the OSPF process?
What is the shortest path from node A to node D, where shortest path is defined as the path with the smallest sum of the delays on each individual link? Explain exactly how you went about finding that path.
In designing a communication network, the Minimum Spanning Tree is being used to show the connected subset of the original network graph showing the least amount of links needed to interconnect all the nodes based on all the link costs.
