OSPF Packet Tracer issue

Need help! I'm having an issue with OSPF with packet tracer. I have enabled ospf on all 3 routers, but no updates are being sent and if I do a sh ip route, no ospf routes are listed. Also, sh ip ospf neighbor shows nothing as well. All 3 routers are conf for area 0. Has anyone run into issues with ospf and packet tracker. Thanks for the help! Here's output from the sh ip pro and sh ip int b from R1:

Give us the relevant running config or try a show ip ospf interface to make sure your network statements are encompassing the correct interfaces.An expert is a man who has made all the mistakes which can be made.

Selfmade Member Posts: 268looks like the 192.168.1.0 network on router 1 needs a correct wildcard mask of 0.0.0.255 area 0
same thing for router 2, because you're using a class C address, not a class B
you have your wildcard masks wrong, that's the problem there chief
here's the easy way to get your wildcard masks correct
let's say your wildcard mask is 255.255.255.224
to figure it out
255.255.255.255
- 255.255.255.224
0.0.0.31 would be your wildcard mask
that's the easy way to ensure you get the correct wildcard masks
it works for all wildcard masks you have to calculate, just do 255.255.255.255 minus whatever the subnet mask is for the network and you have your wildcard maskIt's not important to add reptutation points to others, but to be nice and spread good karma everywhere you go. -
brewoz404 Member Posts: 3 ■□□□□□□□□□Thanks for the tip, had the network portion of the ospf command wrong on R3, once that was corrected, R2 and R3 exchanged updates. Still can't get R1 to work thought, here is the sh running-conf of R1:

brewoz404 Member Posts: 3 ■□□□□□□□□□Thanks for the help guys! That was it!! Incorrect network statements on R1 and R3. Changed on R1 to network 192.168.1.1 0.0.0.0 area 0 and R3 network 192.168.0.0 0.0.255.255 area 0. Once those changes were made, ospf worked!! THANKS AGAIN!

Selfmade Member Posts: 268i'm going to PM you my email address, if you can send me the Packet Tracer file within the next 2 hours before I leave for work (if i go to work) then i can help you figure it out
i need a big picture here, your output is only one part of the pictureIt's not important to add reptutation points to others, but to be nice and spread good karma everywhere you go. -
Selfmade Member Posts: 268well glad you got it working lol
OSPF is all about getting your wildcard masks and network addresses correct
once you master that, the rest is easyIt's not important to add reptutation points to others, but to be nice and spread good karma everywhere you go.
