This was written by some one else, just trying to get a better understanding..
Please help me break this config down and how it works..
This is on a 2821 using vrf
class-map match-all cos-map-pre-vo-1
match ip precedence 5
policy-map cos-po2-ifx-mfr1-140
class cos-map-pre-vo-1
priority 317 3170
police 317000 conform-action transmit exceed-action drop
!
interface MFR1.140 point-to-point
description VRF IFX
bandwidth 3088
ip vrf forwarding ifx
ip address 10.202.24.50 255.255.255.252
ip flow ingress
frame-relay interface-dlci 140 IETF
class cos-frm-ifx-mfr1-140
route-map cos-map-ifx-1 permit 10
interface GigabitEthernet0/0.666
description VRF IFX Voice
bandwidth 1000000
encapsulation dot1Q 666
ip vrf forwarding ifx
ip address 172.19.171.1 255.255.255.192
ip flow ingress
ip policy route-map cos-map-ifx-1
Let me know if I am missing anything...
Thanks!

Let's break it down:
1. There's a class-map and policy-map, which is good. But they need to be applied to an interface.
class-map match-all cos-map-pre-vo-1
match ip precedence 5
policy-map cos-po2-ifx-mfr1-140
class cos-map-pre-vo-1
priority 317 3170
police 317000 conform-action transmit exceed-action drop
interface MFR1.140 point-to-point
description VRF IFX
bandwidth 3088
ip vrf forwarding ifx
ip address 10.202.24.50 255.255.255.252
ip flow ingress
frame-relay interface-dlci 140 IETF
class cos-frm-ifx-mfr1-140
2. When you use the class command under frame relay, it expects to see a matching "map-class frame-relay" There is a policy-map with the same name, but it won't use that.
route-map cos-map-ifx-1 permit 10
3. Route-maps aren't used for QoS, they are used for Policy routing and Route filtering.
interface GigabitEthernet0/0.666
description VRF IFX Voice
bandwidth 1000000
encapsulation dot1Q 666
ip vrf forwarding ifx
ip address 172.19.171.1 255.255.255.192
ip flow ingress
ip policy route-map cos-map-ifx-1
4. "ip policy" is used for policy routing, but it's calling an empty route-map (see above), so I believe it will have no affect. Packets could get punted to the CPU if this is a hardware based platform.
Take a look at the Frame-relay configuration guide for help in guiding you to the correct config. If you need further help, let us know.
