Level 1

I have configured this ospf topology like this below with goals is every node can access each other.

 

OSPF.PNGPKT file : https://drive.google.com/open?id=1c6g0tgbqI9S2FKl9JREWGPjnKmXWRWmy
Problem : From R1_area1 cant connect to local area network(server) and gateway from each router in OSPF area 0
Do I miss configuration?

Some verification of my configuration this below

Hi,

It is looking a Packet tracer bug. I tested the same configuration in my lab and GNS3. it is working fine. I created another lab in Packet tracer and there is the same issue.

Maybe I am missing something, but it should work as it is written. It looks like Packet tracer bug.

When show ip ospf database is issued there should be entry for each route that is advertised into OSPF, however present are only routes between OSPF neighbors (on other hand all routes from the same area are present in routing table).

Solution to go around ping problem (but not to remove root cause itself) would be to configure on ABR:

ip route 0.0.0.0 0.0.0.0 null0

router ospf 1

  default-information originate

 

Ok thanks for check my pkt file.
