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 in 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.
If you execute this command multiple times, the most recent configuration takes effect.
