Router A remarks DSCP values of packets on its outbound interface, then the
subsequent router performs functions like filtering, maximum bandwith restriction on
those packets according to their DSCP values.

3.8.7 Congestion Management Using ATM CLP Bit Configuration Example

I. Network requirements
Router A and Router B are connected through an ATM network and running IPoA.
On Router A, do the following:
1) Configure a policy allowing the router to remark the ATM CLP bit to 1 for packets
with IP precedence of 0.
2) Apply the policy to the outbound direction of interface atm 1/0/0.
On Router B, do the following:
