May 2002
Chapter 4 IP Networking
Scenario 4: Default Gateway on CTC Computer
Figure 4-3 Scenario 3: Using Proxy ARP
ARP matches higher-level IP addresses to the physical addresses of the destination host. It uses a lookup
table (called ARP cache) to perform the translation. When the address is not found in the ARP cache, a
broadcast is sent out on the network with a special format called the ARP request. If one of the machines
on the network recognizes its own IP address in the request, it sends an ARP reply back to the requesting
host. The reply contains the physical hardware address of the receiving host. The requesting host stores
this address in its ARP cache so that all subsequent datagrams (packets) to this destination IP address
can be translated to a physical address.
Proxy ARP enables one LAN-connected ONS 15454 SDH to respond to the ARP request for ONS 15454
SDHs not connected to the LAN. (ONS 15454 SDH Proxy ARP requires no user configuration.) For this
to occur, the DCC-connected ONS 15454 SDHs must reside on the same subnet. When a LAN device
sends an ARP request to an ONS 15454 SDH that is not connected to the LAN, the gateway ONS 15454
SDH returns its MAC address to the LAN device. The LAN device then sends the datagram for the
remote ONS 15454 SDH to the MAC address of the proxy ONS 15454 SDH. The proxy ONS 15454 SDH
uses its routing table to forward the datagram to the non-LAN ONS 15454 SDH. The routing table is
built using the OSPF IP routing protocol. (An OSPF example is presented in the “Scenario 7: Using
OSPF” section on page 4-10.)
4.5 Scenario 4: Default Gateway on CTC Computer
Scenario 4 is similar to Scenario 3, but nodes #2 and #3 reside on different subnets, 192.168.2.0 and
192.168.3.0, respectively (Figure 4-4). Node #1 and the CTC computer are on subnet 192.168.1.0. The
network includes different subnets because Proxy ARP is not used. In order for the CTC computer to
communicate with ONS 15454 SDHs #2 and #3, ONS 15454 SDH #1 is entered as the default gateway
on the CTC computer using the “Setting Up the CTC Computer” section on page 2-11.
