Reference Guide

• If the network is experiencing congestion, the packet is transmitted. No further
marking is required. When you enable wred-ecn, and the number of packets in
the queue is above the maximum threshold, packets are dropped based on the
drop probability. This behavior is the identical treatment a packet receives when
WRED is enabled without ECN configured on the router.
