WRED configuration example
Network requirements
As shown in Figure 30, Server sends critical data traffic, Telephone sends voice traffic, and Host A and
Host B send non-critical data traffic. On Router, because the rate of incoming interface GigabitEthernet
1/0/1 is higher than that of outgoing interface Serial 2/1/1, congestion might occur on Serial 2/1/1.
Perform configurations to meet the following requirements:
1. Critical traffic from Server and Telephone is transmitted preferentially when congestion occurs in
the network.
2. Certain bandwidth is guaranteed for traffic from Host A and Host B to reduce traffic delay.
3. When congestion deteriorates, packets are dropped based on precedence.
Use WFQ in conjunction with WRED for queue scheduling and packet dropping.
