54. Suppose a router has built up the routing table shown in Table 3.21. The router can deliver packets directly over interfaces 0 and 1, or it can forward packets to router R2, R3, or R4. Assume the router does the longest prefix match. Describe what the router does with a packet addressed to each of the following destinations: (a) 128.96.171.92. (b) 128.96.167.151. (c) 128.96.163.151. (d) 128.96.169.192. (e) 128.96.165.121.
