Contiv 1.0.1 and 1.0.0 and DNS problems

[overip]

I was trying the tutorial here https://kubernetes.io/docs/tasks/configure-pod-container/declare-network-policy/
and I could not get the DNS to work properly. I don't know if it is a problem of my machine of it is a bug. If I remember correctly the beta version of contiv used to replace the kube-dns with its own DNS, and don't know if that is still the case with the 1.0.0 and 1.0.1

Anyway the following are the commands and their output, which shows that the DSN is not working

Any suggestions?
Thank you so much!

@rchirakk could you please try this scenario and verify the issue?

Have you configured a contiv default network ?
In which network/epg do you create these pods ?

The example shown above does not use contiv networking.
