The following is an example of unnumbered configuration:

interface FastEthernet 0/0
ip address 10.3.6.1 255.255.255.0

interface Integrated-Service-Engine 1/0
ip unnumbered FastEthernet 0/0
service-module ip address 10.3.6.128 255.255.255.0 ! — Service Module ip address is in same subnet of fa 0/0
service-module ip default-gateway 10.3.6.1 ! — Default Gateway IP address must be pointing to fa 0/0

ip route 10..3.6.128 255.255.255.255 Service-Engine 1/0 ! — This IP address must be the same as service-module ip address
