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.
