WRED configuration example
Network requirements
As shown in
, 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.
