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:
z Assign two IP addresses to VLAN-interface 1 on the switch.
z Set the switch as the gateway on all PCs of the two networks.

Configuration procedure
# Assign a primary IP address and a secondary IP address to VLAN-interface 1.
<Switch> system-view
[Switch] interface Vlan-interface 1
[Switch-Vlan-interface1] ip address 172.16.1.1 255.255.255.0
[Switch-Vlan-interface1] ip address 172.16.2.1 255.255.255.0 sub
# Set the gateway address to 172.16.1.1 on the PCs attached to the subnet 172.16.1.0/24, and to
172.16.2.1 on the PCs attached to the subnet 172.16.2.0/24.
# Ping a host on the subnet 172.16.1.0/24 from the switch to check the connectivity.
<Switch> ping 172.16.1.2
