    Hi folks,

     

    Can anyone help me understand "restricted" proxy-arp? Is it like the arp responses are made if the source and actual IP address are on unlike subnets? Is this understanding right?

     

    Thanks!

    Hi Nexon,

     

    Yes restricted proxy-arp makes the switch/router to respond to an ARP request coming from subnet A for a destination IP in subnet B (say).  The switch/router must have a route to subnet B.
