Figure 6.31 shows the routing table of RTA in Figure 6.32. Although there are no reachability problems in this internetwork, RTA's routing table contains an unexpected entry: Network 192.168.3.0 is reachable via the less-desirable serial links. In Figures 6.33 through 6.36, debugging is used to observe the IGRP updates on the four routers. Although the cause of the problem cannot be determined from these debug messages, the router from which the problem originates can be discovered. Based on the information given, create a hypothesis that explains the most likely cause of the problem.
