Configure local proxy ARP on Switch A to implement Layer 3 communication between VLAN 2 and 

VLAN 3. 

Figure 2-6 Network diagram for local proxy ARP configuration in isolate-user-VLAN 

 

 

 

1)  Configure Switch B 

# Create VLAN 2, VLAN 3, and VLAN 5 on Switch B. Add GigabitEthernet2/03 to VLAN 2, 

GigabitEthernet2/01 to VLAN 3, and GigabitEthernet2/02 to VLAN 5. Configure VLAN 5 as the 

isolate-user-VLAN, and VLAN 2 and VLAN 3 as secondary VLANs. Configure the mappings between 

isolate-user-VLAN and the secondary VLANs. 

<SwitchB> system-view 

[SwitchB] vlan 2 

[SwitchB-vlan2] port GigabitEthernet2/03 

[SwitchB-vlan2] quit 

[SwitchB] vlan 3 

[SwitchB-vlan3] port GigabitEthernet2/01 

[SwitchB-vlan3] quit 

[SwitchB] vlan 5 

[SwitchB-vlan5] port GigabitEthernet2/02 

[SwitchB-vlan5] isolate-user-vlan enable 

[SwitchB-vlan5] quit 

[SwitchB] isolate-user-vlan 5 secondary 2 3 

2)  Configure Switch A 

# Create VLAN 5 and add GigabitEthernet2/0/2 to it. 

<SwtichA> system-view 

[SwtichA] vlan 5 

[SwtichA-vlan5] port GigabitEthernet2/02 

[SwtichA-vlan5] interface vlan-interface 5 

[SwtichA-Vlan-interface5] 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.
