Rewriting Frame Relay Headers

For J-series Services Router 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.

This section is organized as follows:

• Assigning the Default Frame Relay Rewrite Rule to an Interface
• Defining a Custom Frame Relay Rewrite Rule
