Help on WRED on Cisco 12k IOS-XR
I need some help to design QoS in the MPLS Backbone made of Cisco 12k routers running IOS-XR and would appreciate if some can shed some light on it.
I need to enable WRED on my Core Facing Interfaces of c12K running IOS-XR and I need the guidance on deciding the Min Threshold,Max Threshold and Mark Probability Denominator.
I have read through the online documentation but could not make much out of it in practical.
I have also read that
MinTH (x) = 1/2 of MaxTH + x/8 of MaxTH where X=EXP/IPP value.
And the MaxTH= Queue Limit in ms.
Now how do I determine the Queue Limit for a particular EXP//IPP on IOS-XR interfaces
