Question 4 (8 Marks): For this question, your first task is to study the famous "Distance Vector (DV) Routing Algorithm" used at the network layer. You may refer to some slides I recently posted on BB or use any related material to study. In the figure below, there is a sample UoWnetwork with 5 nodes. These nodes can be considered as 5 different servers associated with 5 departments. The network is configured in a way that the associated cost is mentioned for each interface. b. Fill up the below routing table for IT department after 2nd iteration of algorithm.
