Proxy ARP
Proxy ARP functions to realize the Layer 3 connectivity between the hosts within the same
network segment but isolated at Layer 2.
When an ARP request of a host is to be forwarded to another host in the same network
segment but isolated at Layer 2, to realize the connectivity, the device connecting the two
virtual networks should be able to respond to this request. This can be achieved by the device
running proxy ARP.
Within the same network segment, hosts connecting with different layer 3 ports can
communicate with each other through Layer 3 forwarding by using proxy ARP function. The
following example simply illustrates how proxy ARP works.

Within the same network segment, hosts connecting with the same layer 3 port can
communicate with each other through Layer 3 forwarding by using local proxy ARP function.
The following example simply illustrates how local proxy ARP works.
