Local proxy ARP allows communication between hosts that connect to the same Layer-3 interface and
reside in different broadcast domains.
Only one IP address range can be specified by using the ip-range keyword on an interface.
Examples
# Enable local proxy ARP on GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] local-proxy-arp enable

Usage guidelines
Proxy ARP enables a device on a network to answer ARP requests for an IP address not on that network.
With proxy ARP, hosts on different broadcast domains can communicate with each other as they do on
the same network.
Proxy ARP includes common proxy ARP and local proxy ARP.
Common proxy ARP allows communication between hosts that connect to different Layer-3 interfaces and
reside in different broadcast domains.
Local proxy ARP allows communication between hosts that connect to the same Layer-3 interface and
reside in different broadcast domains.
