Chapter 2. Planning for Router Configuration 43
Configuring the Dual-Ethernet Router for IP Routing
The eth commands are used to configure the Dual-Ethernet router for IP routing. Refer to the section Dual-
Ethernet Router Commands (ETH), on page 213, for usage and syntax information.
The last argument of each ETH command determines which interface is being configured (0 for ETH/0, 1 for
ETH/1).
Each interface (ETH/0 and ETH/1) must be set. A minimum of one route must be defined to have a working
configuration. This is generally a default route on the ETH/1 interface where all traffic otherwise specified is
automatically forwarded. This default route is: 0.0.0.0 255.255.255.255 1.
The Gateway address is the IP address supplied by your Internet Service Provider or Network Administrator.
You can customize your router by using the scripting feature, which loads batch files of preset configuration
commands into the router (refer to the Batch File Command Execution, on page 279 section).
A Dual-Ethernet router sample configuration with IP Routing is provided in the Sample Configuration 3:
Configuring a Dual-Ethernet Router for IP Routing, on page 73 section.
