Assigning the Default Frame Relay Rewrite Rule to an Interface
For Juniper Networks device interfaces with Frame Relay encapsulation, you can rewrite the discard eligibility (DE) bit based on the loss priority of Frame Relay traffic. For each outgoing frame with the loss priority set to low, medium-low, medium-high, or high, you can set the DE bit CoS value to 0 or 1. You can combine a Frame Relay rewrite rule with other rewrite rules on the same interface. For example, you can rewrite both the DE bit and MPLS EXP bit.
The default Frame Relay rewrite rule contains the following settings:
This default rule sets the DE CoS value to 0 for each outgoing frame with the loss priority set to low or medium-low. This default rule sets the DE CoS value to 1 for each outgoing frame with the loss priority set to medium-high or high.
To assign the default rule to an interface, include the frame-relay-de default statement at the [edit class-of-service interfaces interface interface-name unit logical-unit-number rewrite-rules] hierarchy level:
