I understand the encapsulation command and that it's needed for VLANs to be entered on the router, but my 2600 doesn't have that as a command in the int f0/0.1 subinterface.
Am I missing something? Or is it not supported?
If it's not supported, what can I do to get it supported (I.e. download another IOS version, upgrade, buy something else...)
Here's what I have:

802.1q trunking was incorporated in the 12.3 Mainline or 12.2T
and you are running 12.2 Mainline.
You need to upgrade IOS.
If you want these details in the future, you can visit the Cisco Feature Navigator http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp and search for features. The intended Feature is IEEE 802.1Q VLAN Trunking
