For troubleshooting I enabled R2's area 0 interface with a priority of 255 and 0's on the spokes

Currently R2 is the DR based on its RID which is 224.0.0.2. Normally I would have used a priority of 255 on the hub and 0 on the spokes but the lab I was working on didn't allow this configuration.

Who is the DR on your frame? You should make R2 your DR if you are using non-broadcast.

It looks like R2 is in the LSDB on R7, just not the routing table. Also there is no filtering and Area 567 is not a stub.
R7#sh ip o d | i 200.0.0.2
200.0.0.2 200.0.0.5 201 0x80000001 0x005B28

150.100.100.0 200.0.0.5 204 0x80000001 0x00EC03

Is R2 in the LSDB of R7? Any filtering in place? Is 567 a stub of any sort?
Post R2, R5, R7 interface and OSPF configurations.

Yes r5 can ping both the r2 and the r7 loopbacks

Hey everyone,
I'm having some strange issues with reachability with OSPF on Lab 10 that I can't figure out. Here is an example of something I'm seeing
R2--s0/1/0.256---Frame Cloud---s0/1/0--R5-fa0/0--Ethernet-fa0/0--R7
R2 has its s0/1/0.256 in Area 0
R5 has its s0/1/0 in Area 0
R5 has its fa0/0 in Area 567
R7 has its fa0/0 in Area 567
R5 is an ABR with interfaces in both areas and R7 has an interface in 567. So far no rules have been broken (area 567 touches area 0 on R5) and inter-area communication should be working between the three routers, but it doesn't. As a test on R7 I just added the loopback interface to the OSPF process in area
567
R7(config)#router os 1
R7(config-router)#net 200.0.0.7 0.0.0.0 area 567
On R5 I verified the route and I can ping the loopback on R7
R5#sh ip ro 200.0.0.7
Routing entry for 200.0.0.7/32<http://200.0.0.7/32> Known via "ospf 1", distance 110, metric 11, type intra area Last update from 150.100.220.7 on FastEthernet0/0, 00:03:51 ago Routing Descriptor Blocks:
* 150.100.220.7, from 200.0.0.7, 00:03:51 ago, via FastEthernet0/0
Route metric is 11, traffic share count is 1
R5#ping 200.0.0.7
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 200.0.0.7, timeout is 2 seconds:
!!!!!
So we are good from R5 to R7 but not to R2 who has the route but can't ping
R2#sh ip route 200.0.0.7
Routing entry for 200.0.0.7/32<http://200.0.0.7/32> Known via "ospf 1", distance 110, metric 1573, type inter area Last update from 150.100.100.5 on Serial0/1/0.256, 00:00:14 ago Routing Descriptor Blocks:
* 150.100.100.5, from 200.0.0.5, 00:00:14 ago, via Serial0/1/0.256
Route metric is 1573, traffic share count is 1
R2#ping 200.0.0.7
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 200.0.0.7, timeout is 2 seconds:
.....
If I run a debug on R2 and then run a ping to 200.0.0.7 it shows routed vis FIB like this
R2(config)#access-list 101 permit icmp any any R2(config)#do deb ip pack 101 de R2(config)#do ping 200.0.0.7 Sending 5, 100-byte ICMP Echos to 200.0.0.7, timeout is 2 seconds:
*May 13 00:29:37.057: IP: tableid=0, s=150.100.100.2 (local), d=200.0.0.7 (Serial0/0.256), routed via FIB
So it R2 knows how to get to R7 the issue must be that R7 doesn't know how to get to back to R2
R7#sh ip ro 200.0.0.2
% Subnet not in table
It seems like Area 0 routes aren't coming over to Area 567, any ideas?
