Repeat Problem P46, using the graph from Problem P24. Assume that the center node is v.
In Problem P46
Consider the topology shown in Figure 4.46, and suppose that each link has unit cost. Suppose node C is chosen as the center in a center-based multicast routing algorithm. Assuming that each attached router uses its least-cost path to node C to send join messages to C, draw the resulting center-based routing tree. Is the resulting tree a minimum-cost tree? Justify your answer.
