In this downstream router example:

HThere are clients statically configured and connected to the DSL router.

HThere are also clients connected behind a downstream router.

HThe DSL interface (dsl1) is numbered.

The command line syntax for this example is:

ifn address eth1 120.26.7.5 255.255.255.0 ifn address dsl1 155.1.3.2 255.255.255.0 ip route create upstream eth1 155.1.3.1

ip route create 130.26.7.0 255.255.255.0 120.26.7.100
