IOS feature set for subinterface routing . . .

Level 4

I just acquired a couple of 2600s with single eth. interfaces. I would like to configure subinterfaces (one for public IP, the other for internal.) However, my current IOS insists that I can not assign IP addresses until I make the main interface a part of an ISL or dotq VLAN. Can someone tell me which feature I'm looking for in the feature navigator? I have a feeling I'm going to need to upgrade my routers from their current 32/8 mem.

Hi Shikamaru,

You need to have atleast IP PLUS feature IOS on your box to make encapsulation command working on subinterface.
