2600 subinterface problem

hey ppl,

i'm currently playing around with a 2600, 2950 and a 3550. I have a problem with the setting up on the 2600 subinterface. all i want to do is create a router on a stick with the 2600, with 2950 as a vtp server, 3550 vtp client. My problem is that the subinterface of the 2600 is not letting me config the ip address nor the encapsulation. I was told at work that the 2600 wants to be configured as a trunk before it will accept those configs, and i am missing a command to do so. Usually, it is enough to enter the sub interface command, place encapsulation dot1q 3 etc and ip address, and that sub interface becomes a trunk! (works on simulators!) but not in this case! btw iso ver is 12.3!

Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int eth0/0.1
Router(config-subif)#ip address

% 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.

Router(config-subif)#encapsulation dot1q 2
% Invalid input detected at '^' marker.


Any ideas which config am i missing? or maybe a link to the solution?
