Help with OSPF environment

[drewdown]

I am pulling my hair out trying to figure out why this isn't working. If you look at the attached picture the only instance of OSPF running is between RTR-07 and RTR-09 which are both 1812's. I cannot for the life me of get OSPF running between RTR-07 <-> RTR-05 and RTR-05 (2811) <-> SWRT01 (layer 3 3750). Can someone help me out? Connectivity is up between all routers and I can ping no problem. Can post config's if need be.

Thanks!

The area statement needs to be area 0, not area 0.0.0.0
Also, start by posting sh ip route from all three.

I realized that and changed it already on each on SWRT-01 and RTR-05.

IP routes:

SWRT01:

C    162.16.0.0/28 is subnetted, 1 subnets
C       162.16.3.32 is directly connected, GigabitEthernet1/0/12
C    220.20.11.0/24 is directly connected, Loopback10
C    220.20.10.0/24 is directly connected, Loopback0

RTR-05:

C    220.10.50.0/24 is directly connected, Loopback0
C    220.10.51.0/24 is directly connected, Loopback2
     162.16.0.0/30 is subnetted, 1 subnets
C       162.16.3.44 is directly connected, FastEthernet0/1
     144.251.0.0/30 is subnetted, 1 subnets
C       144.251.14.16 is directly connected, FastEthernet0/0
C    194.13.32.0/24 is directly connected, FastEthernet0/0/0

RTR-07:

C    220.10.71.0/24 is directly connected, Loopback2
C    220.10.70.0/24 is directly connected, Loopback0
     145.251.0.0/28 is subnetted, 1 subnets
C       145.251.16.48 is directly connected, FastEthernet0
     194.13.32.0/28 is subnetted, 1 subnets
C       194.13.32.16 is directly connected, FastEthernet1
O    220.10.90.0/24 [110/2] via 145.251.16.60, 00:09:48, FastEthernet0

And from debug ip OSPF packets on RTR-07:

*Nov  7 17:22:00.175: OSPF: rcv. v:2 t:1 l:48 rid:220.10.91.5
      aid:0.0.0.3 chk:4D21 aut:0 auk: from FastEthernet0
DEMO-RTR-07#
*Nov  7 17:22:01.303: OSPF: rcv. v:2 t:1 l:44 rid:220.10.51.5
      aid:0.0.0.3 chk:FB68 aut:0 auk: from FastEthernet1

Just figured out 1 problem, RTR-05 and RTR-07/09 are now talking and exchanging routes. I had the mask configured wrong on RTR-07, I was using a /28 on 07 and a /24 on RTR-05.

Now just need to get SWRT-01 in the mix.

Its all fixed now. Sometimes just typing it out helps! Mismatched subnet masks on interfaces caused invalid hello packets, which obviously will not allow an adjacency to form!
