Local Proxy Arp Configuration Example In Isolate-User-Vlan; Network Requirements; Configuration Procedure - HP 10500 Series Configuration Manual

The ping operation from Host A to Host B is unsuccessful because they are isolated at Layer 2.
# Configure local proxy ARP to implement Layer 3 communication between sub-VLANs.
[Switch-Vlan-interface10] local-proxy-arp enable
The ping operation from Host A to Host B is successful after the configuration.

Network requirements

As shown in
which includes uplink port GigabitEthernet 1/0/2 and two secondary VLANs, VLAN 2 and VLAN 3.
GigabitEthernet 1/0/3 belongs to VLAN 2, and GigabitEthernet 1/0/1 belongs to VLAN 3. Host A
belongs to VLAN 2 and connects to GigabitEthernet 1/0/3 of the switch. Host B belongs to VLAN 3 and
connects to GigabitEthernet 1/0/1 of the switch.
As Host A and Host B belong to different secondary VLANs, they are isolated at Layer 2. Configure local
proxy ARP on Switch A to implement Layer 3 communication between Host A and Host B.

Configuration procedure

On Switch B, create VLAN 2, VLAN 3, and VLAN 5. Add GigabitEthernet 1/0/3 to VLAN 2,
1.
GigabitEthernet 1/0/1 to VLAN 3, and GigabitEthernet 1/0/2 to VLAN 5. Configure VLAN 5 as
an Isolate-user-vlan, and VLAN 2 and VLAN 3 as secondary VLANs. Configure the mappings
between the Isolate-user-vlan and secondary VLANs.
