OSPF not work between 2 mikrotiks.

Hi All,
I am having an issue with implementing ospf. I am lead engineer for a small WISP 300 odd clients on 30 odd AP's. I am setting up OSPF for the first time. We use Mikrotik mainly. We have 2 microwave links coming into our main sites.
Image. The problem is Site A can see and ping site b and site A can see site B as a neighbor but site B cant see site A as a neighbor it can ping site A and site A shows ip in IP neighbous.
Here is the ospf export for Site A
/routing ospf area
add area-id=0.0.0.1 name=area1
/routing ospf instance
set [ find default=yes ] router-id=10.255.255.1
/routing ospf network
add area=backbone network=192.168.15.0/24
add area=area1 network=10.20.30.0/27
Site B OSPF export
/routing ospf instance
set [ find default=yes ] router-id=10.255.255.33
/routing ospf network
add area=backbone network=192.168.15.0/24

I have tried setting up the interfaces as ptmp and ptp but still got the same results

I am not worried about the cleint APS that reside on the bridge.

Can anyone point me in the right direction.
Cheers
ColumF

Try adding the following
Site A
/routing ospf area
add area-id=0.0.0.0 name=backbone
Site B
/routing ospf area
add area-id=0.0.0.0 name=backbone
Can you confirm what
/routing ospf interface
looks like

Cheers dgnevans.
The backbone area is on both and the id is 0.0.0.0
here is the output of /routing ospf interface
site A
0 D publics 10 1 broadcast none
1 D Backhauls 10 1 broadcast none

Site B
0 D ether9 10 1 broadcast none

These are the dynamic created interfaces. I did set up interfaces and the only "network Type" I did not try was nbma
The backhauls interface on site A is my ap and client side area (area1) I will be setting up much the same on site B.
The Publics interface is the bridge link between sites and also my uplink feed comes to site A via the bridge.

Also check MTU on all participating interfaces and check if you really are able to send maximum sized packets.

What Radios are you using?
Have you tried to configure two routers on a bench test with a similar config to rule out a problem with the radios. have a look at this link sounds similar to what you having

Try uploading both configs from /export compact. A detailed description of the current neighbor status between the two units would also be helpful.
