C3550 and DHCP Relay—MPLS VPN Support

We have WS-C3550-24-EMI running VRF-lite. How can we achieve that hosts attached to the these switches can get ip addresses from a DHCP server which is in another VRF than the DHCP clients. As far as I know C3550 doesn't support DHCP Relay on MPLS VPN.

Maybe packet leaking does help you, i.e. a static host route pointing to the DHCP server out of the VRF. You would need host routes pointing back to your VRF interfaces though, which occur as source IPs for the unicast DHCP request (after ip helper-address ... )
