% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.

Is the switch a layer 3 switch? Is the router a separate device? If
so, you need to trunk the VLANs out to the router and assign the IPs
there and ensure routing is turned on. If this is a layer 3 switch,
then you need to put the fast ethernets in vlans, create the vlans
(interface VLAN1), give them IP addresses, and turn up routing.
