Eddie,

you have to create an dot1q trunk between a "normal" GE-Port
and an OSM-GE-Port to make that work.

as far as i can remember it should work as follows:

interface GigabitEthernet1/1
  switchport
  switchport trunk encapsulation dot1q
  switchport mode trunk
  no ip address
!
interface GE-WAN2/1
 no ip address
 negotiation auto
 mls qos trust dscp
!
interface GE-WAN2/1.66
 encapsulation dot1Q 66
 ip address 66.66.66.66 255.255.255.0
 ip vrf forwarding vpnred
 mls qos trust dscp
!
interface FastEthernet3/1
 switchport
 switchport access vlan 66
 switchport mode access
 no ip address
!

regards,
    markus
