FR WRED configuration example
Network requirements
As shown in Figure 50,
• Router A connects to Router B through an FR network.
• Configure WFQ for the FR PVCs of Router A and enable DSCP-based WRED.
• On PVCs of Router B, allocate bandwidth for packets with the specific DSCP values and enable
DSCP-based WRED for these packets, and configure WFQ and the WRED policy for the other
packets.

Configuration procedure
1. Configure Router A:
# Create traffic behavior wfqwred and configure WFQ and WRED actions in the behavior.

[RouterA-behavior-wfqwred] queue wfq queue-number 256
[RouterA-behavior-wfqwred] queue-length 512
