Local Management1-40Local Management User’s GuideA proxy ARP response is generated when the following occurs:• Proxy ARP is enabled on a router port.• An ARP request is received as a LAN broadcast (looking for the MAC-layer address of an IPhost on another network segment).• An entry exists in the IP Forwarding Table for the destination host’s network.Enabling Proxy ARP on a router port allows IP hosts to dynamically obtain the MAC-layer addressof other IP hosts attached to different networks or subnetworks by using broadcast ARP requestpackets. With Proxy ARP enabled, IP hosts are not required to maintain knowledge of specificsubnetworks.To enable Proxy ARP on a router port, complete the following steps:1. Use the arrow keys to highlight the Proxy ARP option.2. Use the ENTER key to toggle the entry to ENABLED.3. Use the arrow keys to highlight the SAVE command field at the bottom of the screen, and thenpress ENTER. The message “SAVED OK” displays.Configuring the Network Broadcast Type on a PortIP Routing Services recognizes and accepts network broadcasts, IP packets with the host portionof the IP address as either all 1’s or all 0’s. Other networking devices only recognize all 0’s as anetwork broadcast.To configure IP Routing Services to send network broadcasts addressed to all 0’s, complete thefollowing steps:1. Use the arrow keys to highlight the Network Bcast option.2. Use the ENTER key to toggle the entry to ZEROS.3. Use the arrow keys to highlight the SAVE command field at the bottom of the screen and thenpress ENTER. The message “SAVED OK” displays.IP RIPRouting Information Protocol (RIP) is a widely implemented routing protocol that is usedextensively on IP internetworks. IP Routing Services uses the RIP routing protocol to send andgather information about the internetwork topology. This information is used to construct andmaintain a database called RIP Route Table, which contains the addresses of the available routes toall the networks and hosts that RIP has learned.
