Duane,
You can run Multi-VRF or VRF lite on the CE kit.
See:

http://www.cisco.com/warp/public/cc/pd/rt/2600/prodlit/1575_pp.htm

As a matter of interest do you have figures for
the PE VRF limits I have only seen mention a figure
of 32 ?

Regards,
Kevin

As far as I know VRF's aren't configured on the CE's (do you perhaps
mean PE?). There are limits to the number of VRF's you can run, but it
depends on which IOS you are running.

Subject: [nsp] ip vrf forwarding limitations ?

I am looking at using MPLS and ip vrf forwarding to terminate multiple
VPNs on a CE router and then break each VPN out onto a physical
interface. I need to do this rather than simply doing rd imports as we
need firewalls between each VPN on the customers side.

Someone told me that there is a supported limit of 5 VRF's on the
CE side after that there is a CPU hit and the TAC will not support
it. However I can not find any reference to this on CCO. Anyone
care to comment , as I am assuming that there is no such limit on
the PE's or is my understanding of the VRF concept totally wrong ?

Also an interesting question is running non routeable and non DLSW'able
protocols over a Public MPLS cloud. Bridging over a tunnel would
be perfect but not supported. Martini over the MPLS is a bit bleeding
edge
and it would mean a seperate VPN for the non routeable traffic. Any
comments most welcome ?

Regards,
Kevin
