Repeat Problem P44 using the graph from Problem P24. Assume that z in the broadcast source, and that the link costs are as shown in Problem P22.
In Problem P44
Consider the topology shown in Figure 4.44. Suppose that all links have unit cost and that node E is the broadcast source. Using arrows like those shown in Figure 4.44) indicate links over which packets will be forwarded using RPF, and links over which packets will not be forwarded, given that node E is the source.
