Configuration procedure
1. Configure Switch
# Add Ethernet 1/3, Ethernet 1/1 and Ethernet 1/2 to VLAN 2. Configure port isolation on Host A and
Host B.
<Switch> system-view
[Switch] port-isolate group 2
[Switch] vlan 2
[Switch-vlan2] port ethernet 1/3
[Switch-vlan2] port ethernet 1/1
[Switch-vlan2] port ethernet 1/2
[Switch-vlan2] quit
[Switch] interface ethernet 1/3
[Switch-Ethernet1/3] port-isolate enable group 2
[Switch-Ethernet1/3] interface ethernet 1/1
[Switch-Ethernet1/1] port-isolate enable group 2
[Switch-Ethernet1/1] interface ethernet 1/2
[Switch-Ethernet1/2] port-isolate uplink-port group 2
2. Configure LB module
# Specify the IP address of Ten-GigabitEthernet 0/0.1.
<LB> system-view
[LB] interface Ten-GigabitEthernet 0/0.1
[LB-Ten-GigabitEthernet0/0.1] ip address 192.168.10.100 255.255.0.0
The ping operation from Host A to Host B is unsuccessful because they are isolated at Layer 2 and Layer
3.
# Configure local proxy ARP to allow communication between Host A and Host B at Layer 3.
[LB-Ten-GigabitEthernet 0/0.1] local-proxy-arp enable
The ping operation from Host A to Host B is successful after the configuration.
Local proxy ARP configuration example in isolate-user-VLAN
Network requirements
As shown in Figure 36, Switch is attached to LB module. VLAN 5 on Switch is an isolate-user-VLAN,
which includes uplink port Ethernet 1/2 and two secondary VLANs, VLAN 2 and VLAN 3. Ethernet 1/3
belongs to VLAN 2, and Ethernet 1/1 belongs to VLAN 3.
Configure local proxy ARP on the LB module to implement Layer 3 communication between VLAN 2 and
VLAN 3.
