What about insetting a service-policy to not match ospf?
class-map match-all NO_OSPF
match not protocol ospf
!
policy-map ADP_FRTS_NO_OSFP
class NO_OSPF
map-class frame-relay adjust_vc_class_rate
frame-relay cir 512000
frame-relay mincir 265000
frame-relay adaptive-shaping interface-congestion 10
service policy ADP_FRTS_NO_OSFP

Hey Thomas,
It sounds like your talking about Adaptive Frame-Relay Traffic Shaping.
With Adaptive FRTS, if the congestion exceeds the configured queue depth
(say 10 packets) the rate will be dropped to the mincir of 256K and
restored once the rate falls below the configured queue depth.

Feature Overview
The Adaptive Frame Relay Traffic Shaping for Interface Congestion
feature enhances Frame Relay traffic shaping functionality by adjusting
permanent virtual circuit (PVC) sending rates based on interface
congestion. When this new feature is enabled, the traffic-shaping
mechanism monitors interface congestion. When the congestion level
exceeds a configured value called queue depth, the sending rate of all
PVCs is reduced to the minimum committed information rate (minCIR). As
soon as interface congestion drops below the queue depth, the
traffic-shaping mechanism changes the sending rate of the PVCs back to
the committed information rate (CIR). This process guarantees the minCIR
for PVCs when there is interface congestion.

Does anyone know if it's possible to adaptively shape traffic based on
the number of packets in queue? I saw this question once and if I am
remembering it correctly it wanted to configure a min cir of 256k if
there were more than 10 packets in queue. Additionally the solution was
not to include OSPF in this traffic shaping. I've hunted up and down
and in the doc cd and I did not see how you can perform traffic shaping
based on the number of packets in queue nor did I see anything with FRTS
that allowed you to select what traffic was shaped and what was not.
Has anyone ever heard of this?
