IP Address Configuration Example II
Network requirements
As shown in Figure 1-4 VLAN-interface 1 on a 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 the
switch, and the hosts on the LAN can communicate with each other, do the following:
Assign two IP addresses to VLAN-interface 1 on the switch.
Set the switch as the gateway on all PCs of the two networks.
