a) Assume that node e knows the costs of all the links in the network. Using the Dijkstra's shortest-path algorithm, fill in the table below to compute the shortest paths to all the other routers, and draw the shortest path tree on top of the network (thicken/color the links). Step N' 0 12345 e D(a), p(a) D(b), p(b) D(c), p(c) D(d), p(d) D(f), p(f) b) Write down the forwarding table at node e to all the IP addresses in the figure using the longest prefix matching where links are written as <e,a>, <e,f>, etc. Your forwarding table should have exactly 3 entries. c) Write down the Bellman-Ford equation and describe in which routing algorithm it is used. Describe what happens at a node when there is a change in a local link cost in case this routing algorithm is used. 255.0.0.1 255.0.0.2 255.0.0.3 255.1.0/24 254.2/15 3. 255.1.1/24 5 255.1.2/24 255.1.4/22 255.1.3/24 a) Assume that node e knows the costs of all the links in the network.
