OK. Something unusual is going on. Please edit your original question to include the full ABR configuration. Also include the output from show ip ospf database.

Hmmm, it shows no OSPF on the ABR (on the other routers yes) Gateway of last resort is not set 172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks C 172.16.99.0/24 is directly connected, GigabitEthernet0/1 L 172.16.99.4/32 is directly connected, GigabitEthernet0/1 192.168.99.0/24 is variably subnetted, 2 subnets, 2 masks C 192.168.99.0/24 is directly connected, GigabitEthernet0/0 L 192.168.99.4/32 is directly connected, GigabitEthernet0/0

| Mar 19, 2022 at 17:07 | comment | added | gabone | Hey Ron, thanks for the reply, all routers seem to have all proper neighbours. I have tried the debug command but there is not debug ospf on my version of packet tracer. All pings in the same area are successful but nothing gets through the ABR. I also checked the areas, they are all correct. I can't find the problem. Could you tell me just where the problem is? Not the answer, just where the problem is. Thanks. | |
