Network requirements

As shown in Figure 1-4, VLAN-interface 1 on Switch is connected to a LAN comprising two segments: 172.16.1.0/24 and 172.16.2.0/24.

To enable the hosts on the two network segments to communicate with the external network through Switch, and the hosts on the LAN can communicate with each other, do the following:
