Suppose a router has built up the routing table shown in Table 3.18. The router can deliver packets directly over interfaces 0 and 1, or it can forward packets to routers R2, R3, or R4. Describe what the router does with a packet addressed to each of the following destinations: (a) 128.96.39.10 (b) 128.96.40.12 (c) 128.96.40.151 (d) 192.4.153.17 (e) 192.4.153.90 Table 3.18 Routing Table for Exercise 55 SubnetNumber SubnetMask NextHop Interface 0 128.96.39.0 255.255.255.128 128.96.39.128 255.255.255.128 Interface 1 128.96.40.0 255.255.255.128 R2 192.4.153.0 255.255.255.192 R3 (default) R4
