Have you tried 
 
vrf forwarding 
 
or 
 
vrf member
</div>

<div>
Thanks, but neither are an available command for an interface. &nbsp;But in my 15.2 router, I do have ip vrf forwarding on interfaces
</div>

<div>
What feature set do you have installed on the 15.4 router? Is it the same as the 15.2?
</div>

<div>
the 15.2 router: c2900-universalk9-mz.SPA.152-4.M4.bin 
the 15.4 router: c1900-universalk9-mz.SPA.154-3.M9.bin 
 
I can't enter just no switchport on the interface, but I can do no switchport access vlan 3 
but it still doesn't give me a vrf option:

Looks like IPBASE may not be sufficient. See if you can enable the datak9 License that I see listed.

I can't enter just no switchport on the interface, but I can do no switchport access vlan 3

Not sure for 1900, but IPbase may or may not be enough depending on your needs (For multi-VRF should be OK).

No luck as of yet. &nbsp;However, since my physical interface refers to vlan3, and vlan3 does have ip vrf forwarding INTERNAL, will that still work? &nbsp;I would love to just plug it in and see, but that isn't an option right now. 
 
interface FastEthernet0/1/3 
&nbsp;switchport access vlan 3 
&nbsp;no ip address 
! 
 
interface Vlan3 
&nbsp;ip vrf forwarding INTERNAL 
&nbsp;ip address x.x.x.x 255.255.255.0 
! 
 
 
The current 15.2 router interface has vrf forwarding on it: 
 
interface FastEthernet0/0/3 
&nbsp;switchport access vlan 3 
&nbsp;ip vrf forwarding INTERNAL 
&nbsp;no ip address 
 
interface Vlan3 
&nbsp;ip vrf forwarding INTERNAL 
ip address x.x.x.x 255.255.255.0
</div>

<div>
Forgot to mention that yes, I can add vrf forwarding to regular routed interfaces
</div>

<div>
You should be able to add to any routed port or vlan svi.

Cisco VRF Configuration issue

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
