(b) Apply the Dijkstra's algorithm to find the shortest path tree and the forwarding table for node 3 in the network shown in Fig.Q3. The number besides each link represents the cost of the link. You should clearly show the details in each iteration when deriving the answer. No marks will be given for an answer without any steps. (c) Suppose now the distance vector algorithm is used to build up the routing table of all routers for the network shown in Fig.Q3. Write down the initial distance vector of node 4. Also determine the forwarding table of node 11 after it receives the initial distance vectors from all its neighbors. Given that the forwarding table has the following entries: Destination Next Hop Cost

For the network shown below, assume that the Bellman-Ford routing algorithm is used. Assume that initially each router knows the distance to its neighbors. Illustrate the following: - Initial routing table at node "1" - Final routing table at node "1" Show clearly how the algorithm would react if there is a failure in the link connecting nodes "3" and node "6" and the next hop.
