Sample Configuration 3: Configuring a Dual-Ethernet Router for
IP Routing
Scenario:
The following example provides a simple sample configuration for a Dual-Ethernet router (eth_router) with
IP routing enabled.
The routerÕs hub (ETH/0) belongs to the 192.168.254.0 subnet. The routerÕs ETH/1 belongs to the
192.168.253.0 subnet.
ETH/0 will route packets to ETH/1 at the address 192.168.253.254. DHCP is enabled for both subnets.
