1) Routers in the following network use distance vector routing. When the system is first powered up, a router’s routing table only contains the distance estimates to its neighbors. The distances to non-neighbors are set to infinity. To simplify the discussion, we assume all updates are sent and received at the same time. When two paths having the same distance, the router will randomly select one. (a) Write down the routing tables of all five nodes when the system is powered up. (b) Show the routing tables of all five nodes after 1, 2, 3 table updates.

Unless indicated otherwise, link weights are 1. Use Dijkistras shortest path algorithm to find the spanning tree which contains all paths from router A to the rest of the routers in the network. Show the results of the first four steps of the algorithm. A B C D E F H G 3 4 2 2 3...
