Would like your assistance please in understanding QoS AFxx concept
I know that we have 4 Assured Forwarding and each class has 3 drop probability
For example If we have AF11 , AF12 and AF13 then AF13 should have higher drop probablity than AF11.
My question is how do router know that AF13 has higher drop probablity than AF11 ?
I believe this can only be done by wRED but what confuses me why it is not written in documents that wRED is a must for this case !
Am I missing something ???
Appreciate your assistance
