Network Addressing
Configuring Gateways on Variable-Length Subnets
Proxy ARP Server
The default direct route entry on Host D assumes that there is a proxy
ARP server on the 192.6.20 network. If there is none, additional indirect
route entries can be configured for each gateway that is directly
connected to the 192.6.20 network.
For example, referring to Figure 6-15, you might add the following
indirect routes to send messages to Division 2 and Division 3.
ROUTE_DESTINATION[4]=”net 192.6.14”
ROUTE_MASK[4]=”255.255.255.0”
ROUTE_GATEWAY[4]=”192.6.20.2”
ROUTE_COUNT[4]=”1”
ROUTE_DESTINATION[5]=”net 192.6.13”
ROUTE_MASK[5]=”255.255.255.0”
ROUTE_GATEWAY[5]=”192.6.20.3”
ROUTE_COUNT[5]=”1”
