I must be doing something wrong. I am looking to transfer 3 VLANS (10, 20, and 30) over a T1 point to point using Cisco 1921 routers. I do not want to "Bridge" the connection, one location has a 10.1.0.0/16 subnet and the other location has a 10.2.0.0/16 subnet because we don't want to saturate the already slow link. I tried the instructions here:
http://www.cisco.com/en/US/tech/tk389/tk815/technologies_tech_note09186a0080094663.shtml but it didn't seem to work.
With these routers couldn't I create the three VLAN's then tell the GigabitEthernet0/0 interface it's a trunk port? Or do I setup sub interfaces (.10, .20, and .30) for each vlan? I've tried all of the above and I can't get it to work. I can directly plug into the router and ping the other router on the other side of the T1 but I can get the info comming from my Dell PowerConnect 6248 (plugged into a trunk port) to go through to the router which is why I think it's a vlan issue.

Yes but if you still can't ping something, ain't done yet.

I'm sorry....can you expand on that? Right now I can ping what I believe is everything I need to:
From the router console to all three VLAN IP's on the Dell switch
From the dell switch console to all three sub interfaces on the router
From a computer plugged into one of the VLAN ports on the switch I can ping all three sub interfaces on the rouer (again routing is enabled on the switch)
My tracert from the PC (10.2.10.240) to the router shows this:
10.2.10.1
10.2.30.9
complete
So it seems the swtich is routing my request to the other vlan then to the router which responds. Am I missing something?

My misunderstanding then.
Thank you for the nice rating and good luck!
