DNS forward lookup zone validation timeout

Level 1

Hello, I am very new to networking and I am currently trying to set up a lab in my computer science class. I am trying to set forward lookup zone to our parent network's DNS server. When doing so the request says "A timeout occurred during validation" my DNS server cannot ping their DNS, but my router 2 can ping their DNS. Ive also attacthed a picture of the topography. Let me know if seeing any configurations would be helpful!

Can you show where is DNS server in your network?

It is connected on VLAN 200

you can not have same subnet connect to different L3 device 
i.e.
VLAN11/12 connect to R1 and R3 and that make issue in network connectivity
