2.4.2 Local Proxy ARP Configuration Example in Case of Port Isolation

I. Network requirement
PC1 and PC2 belong to the same VLAN, and are connected to GE1/0/3 and
GE1/0/4 of the switch respectively.
The switch is connected to the Switch A (S5500-28C-SI) via GE1/0/2
GE1/0/3 and GE1/0/4 isolated at layer 2 can implement layer 3 communication..

III. Configuration procedure
1) Configure the Switch B
# Add GE1/0/2, GE1/0/3 and GE1/0/4 to VLAN 2. PC1 and PC2 are isolated and
unable to exchange Layer 2 packets.
