Subject: [c-nsp] Applying bandwidth to an ATM VC path

I have an ATM path from my LEC between me and another CLEC (Foo). The LEC
applies bandwidth to the VC
and then I work with the other side to divvy up the bandwidth among the
PVC's in this path.

So if I buy 4 megs CBR from the LEC I can divvy bandwidth as follows:

interface ATM3/0.3123 point-to-point
 description VC path 5 to CLEC Foo /// MPLS-VPN
 bandwidth 1000
ip verify unicast reverse-path
  ip address x.x.x.x/xx
 ip pim dense-mode
ip mroute-cache
 ip policy route-map foobar
 pvc 5/32
 protocol ip x.x.x.x  broadcast
  cbr 1000
  oam-pvc manage
  encapsulation aal5snap
 !
!
interface ATM3/0.3124 point-to-point
 description VC path 5 to CLEC Foo /// Peering connection
 bandwidth 3000
ip verify unicast reverse-path
 ip address x.x.x.x/xx
 no ip mroute-cache
 ip policy route-map foobar
 pvc 5/33
  protocol ip x.x.x.x  broadcast
  cbr 3000
  oam-pvc manage
  encapsulation aal5snap

The other side (CLEC Foo) matches the same amount of bandwidth per PVC as I
configed.

So now I want to apply the 4 megs to just the VC (5) and not individual
PVC's, letting them ride up to the VC limit of 4 megs cbr.
I have done this on ATM (Lucent) and Frame Relay switches but can't find a
doc at Cisco to guide me for a router.

The gear I am doing this on is a 7206 VXR NPE-400, PA-A3-OC3, running IOS
c7200-is-mz.122-19b. I will be moving to 12.2 SB shortly.

Can anyone point me in the right direction ?

Thanks,
