Configuring IP, ARP, RARP, RIP, and OSPF Services
1-12
308627-14.20 Rev 00
In Figure 1-4, the router wants to send a packet to host C but knows only host Cs
IP address. The router uses ARP to determine host Cs physical address, as
follows:
1. The router broadcasts a special packet, called an ARP request, that asks IP
address 140.250.200.4 to respond with its physical address.
2. All network hosts receive the broadcast request.
3. Only host C responds with its hardware address.
The router maps host Cs IP address (140.250.200.4) to its physical address
(00 00 A2 00 10 40) and saves the results in an address-resolution cache for future
use.
The router can send ARP requests even if ARP, which is a dynamically loaded
module, is not currently loaded on the router. To ensure that ARP is loaded
correctly on a slot using Site Manager, choose Events Manager > Options >
Filters; then select LOADER and Debug, and choose File > Get Current Log File.
Verify that ARP is loaded on a slot by locating the following message in the log:
#xx:01/01/99 10:10:55.00 DEBUG SLOT x LOADERCODE:33
Loader service completed for ARP.EXE 0xxxxxxxxx
