OSPF over RED server/client problems

This is my first time setting up an OSPF routed network. This network consists of 2 head offices (for redundancy) and 3 branch offices. I have both HO's in area 0 and all BO's in area 1.  I set up one side of the network in OSPF neighboring R1 to R2, R3, R4, R5 (R2 is not a neighbor to R3, R4, R5 yet). At this point everything is working and data flows between all locations.  

Here's where it all fails,  when I try to set up R2 to be a neighbor with R3, R4, and R5 I see routs start to fail. For example R3 will ping R1, R2, R4 but not R5, and R4 will ping R1, R2, R5, but not R3. 

I'm not sure why this isn't working and I would appreciate any help I can get. I know I'm doing something wrong here, I just don't know what it is. 

Edir: I am trying to set up a dual hub/star and spoke routed network.



Router 1 (XG450)

Router 2 (XG450)

Router 3 (XG135)

Router 4 (XG135)

Router 5 (XG135)

All at version 16.05.2


I'm trying to configure a routed network over RED tunnels. Routers 1 and 2 are in two separate Data Centers, routers 3, 4, and 5 are separate branch offices.


Red Networks are all LAN Zone:

Network between R1 and R2  Area 0

Network between R1 and R3  Area 1

Network between R1 and R4  Area 1

Network between R1 and R5  Area 1

Network between R2 and R3  Area 1

Network between R2 and R4  Area 1

Network between R2 and R5  Area 1
