IP addressing configuration example
Network requirements
As shown in Figure 12 , GigabitEthernet 0/1 on the SecPath 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
SecPath, and to enable the hosts on the LAN to communicate with each other,
• Assign a primary IP address and a secondary IP address to GigabitEthernet 0/1 on the router.
• Set the primary IP address of the SecPath as the gateway address of the PCs on subnet
172.16.1.0/24, and the secondary IP address of the SecPath as the gateway address of the PCs on
subnet 172.16.2.0/24.
