Question: Suppose a router has built up the routing table shown in Table 3.20. The router can deliver packets directly over interfaces 0 and 1, or

Suppose a router has built up the routing table shown in Table 3.20.

The router can deliver packets directly over interfaces 0 and 1, or it can forward packets to router 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.
