F3215-HP Load Balancing Module Network Management Configuration Guide-6PW101

Configuration example

Network requirements

As shown in Figure 12, GigabitEthernet 0/1 on LB 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 subnets to communicate with the external network through LB, and to

enable the hosts on the two subnets to communicate with each other:

• Assign a primary IP address and a secondary IP address to GigabitEthernet 0/1 on LB.

• Set the primary IP address of LB as the gateway address of the hosts on subnet 172.16.1.0/24, and

the secondary IP address of LB as the gateway address of the hosts on subnet 172.16.2.0/24.

Configuration procedure

# Assign a primary IP address and a secondary IP address to GigabitEthernet 0/1.

<LB> system-view

[LB] interface gigabitethernet 0/1

[LB-GigabitEthernet0/1] ip address 172.16.1.1 255.255.255.0

[LB-GigabitEthernet0/1] ip address 172.16.2.1 255.255.255.0 sub

# Set the gateway address to 172.16.1.1 on the hosts attached to subnet 172.16.1.0/24, and to 172.16.2.1

on the hosts attached to subnet 172.16.2.0/24.

# Ping a host on subnet 172.16.1.0/24 from LB to verify the connectivity.

<LB> ping 172.16.1.2
