A 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 IP
host on another network segment).
host 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 address
of other IP hosts attached to different networks or subnetworks by using broadcast ARP request
packets. With Proxy ARP enabled, IP hosts are not required to maintain knowledge of specific
subnetworks.
of other IP hosts attached to different networks or subnetworks by using broadcast ARP request
packets. With Proxy ARP enabled, IP hosts are not required to maintain knowledge of specific
subnetworks.
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 then
press ENTER. The message “SAVED OK” displays.

Configuring the Network Broadcast Type on a Port
IP Routing Services recognizes and accepts network broadcasts, IP packets with the host portion
of the IP address as either all 1’s or all 0’s. Other networking devices only recognize all 0’s as a
network broadcast.
of the IP address as either all 1’s or all 0’s. Other networking devices only recognize all 0’s as a
network broadcast.
To configure IP Routing Services to send network broadcasts addressed to all 0’s, complete the
following steps:
following 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 then
press ENTER. The message “SAVED OK” displays.

IP RIP
Routing Information Protocol (RIP) is a widely implemented routing protocol that is used
extensively on IP internetworks. IP Routing Services uses the RIP routing protocol to send and
gather information about the internetwork topology. This information is used to construct and
maintain a database called RIP Route Table, which contains the addresses of the available routes to
all the networks and hosts that RIP has learned.
