Hello,

it was a great lesson very interesting!!!, when I lab ( had to use OER instead) it up, it worked but I came up with a couple of question.

1. **Delay statistics**. Default policy is

```
    resolve delay priority 11 variance 20
    resolve utilization priority 12 variance 20
    and learn 
    throughput
    delay
```

using command show oer master border detail, only shows utilization, however in the policy it uses delay also, in fact is priority 11 more than 12 utilization, as in this lab the delay its the same is deciding with utilization, but delay has the highest priority, how display the delay statistics? show oer master prefix detail?

1. **PBR with applications** , can you show an example?  
I see that with oer-map we can do a lot of things, thresholds, variance, parameters. In oer-map I can only match a prefix list maybe in pfr its an extended access-list with ports and when it recognizes it uses PBR automatically?

Thanks  
Regards
