Local proxy ARP configuration example in isolate-user-VLAN
Network requirements
As shown in
Figure 10
, Switch B is attached to Switch A. VLAN 5 on Switch B is an isolate-user-VLAN,
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 Switch B. Host B belongs to VLAN
3 and connects to GigabitEthernet 1/0/1 of Switch B.
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.
