This is very similar to the old dsl termination configs actually. An example based on something we have setup and working: in loopback 1 ip address 10.1.1.1 255.255.255.0 in gi1/0.102 encaps dot1q 102 ip unnumbered loop 1 ip route 10.1.1.2 255.255.255.255 gi1/0.102 The device off that vlan would have an IP of 10.1.1.2/24, gateway of 10.1.1.1.
