DNS Server forward look up times out

[wtsmith]

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 a 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. I've also attached a picture of the topography. My DNS Server and DHCP are running off of the VLAN 200 with Proxmox. Let me know if seeing any configurations would be helpful!

How would I fix it?

Match area in both router interconnect by this subnet 

I see area is different under ospf for same subnet'

Also there is more word are there any more prefix? Or yoh show all prefix?

Would I just add --More-- network 172.16.60.0 0.0.0.7 area 1 to R2?
I apologize I am not understanding.

These all prefix config under ospf of three routers???

Yes these are all the OSPF configurations.

R2#
router ospf 109
--More-- !
--More-- router ospf 1
--More-- network 172.16.20.0 0.0.0.7 area 1

R1

--More-- network 172.16.60.0 0.0.0.7 area 0

R3

--More-- network 172.16.60.0 0.0.0.7 area 0

Do that and check DNS reachable

That worked!!

When trying to set a forward lookupzone to 10.8.0.30 it still times out.

[MHM Cisco World]

What is work ?

Sorry I dont get it

MHM

[wtsmith]

The OSPF configuration worked, but I still cannot setup the forwarder.

The OSPF configuration works, but I still cannot get the forwarder to work

Connect device to SW1 and ping to dns are ping success?

Does the device get IP via dhcp?

MHM

[wtsmith]

It does. Ping is a success

[MHM Cisco World]

Without any static route anymore?

And It get IP from dhcp?

If both Yes then issue is solved and only DNS domains is wrong 

MHM

It does but I cannot forward our DNS to theirs 172.16.200.21 is my DNS 

and I need it to forward to 10.8.0.30 but it say "A timeout occurred during validation"

[MHM Cisco World]

*"it does but I cannot forward our DNS to theirs 172.16.200.21 is my DNS" "

Maybe I am tired can you more elaborate 

Yoh in PC connect to SW1 with vlan 11 9r vlan 12, 

You send dns request from this PC to dns server in vlan200? 

That Correct
