I'm a third year comp-sci student, and having trouble with some basic setup of my network in packet tracer. My main issue is that I cannot send packets between ACMER1 to ACMER2, and ACMER1 to ACMER3. I am pretty sure I'm supposed to implement some variation of a static route, but for the life of me cannot figure out why I can't get it to work. I am sure this a simple fix and that I'll kick myself if I figure it out.
My network topology:
Here are my "show running-config"'s below:
ACMER1:

It would also help if you post the output of show ip interface brief from each of the routers.

I asked for "show ip ospf interface serial x/x
Can you provide?

Dont worry.
From router you are trying to peer up with OSPF. Those two serial interfaces connected each other.

Alright.
On router ACMER2 you run:
show ip ospf interface Serial0/0/1
On router ACMER3 you run:
show ip ospf interface Serial0/0/1
11-24-2017 08:12 AM
It might provide helpful information to run debug ip ospf adjacency

You are welcome. I am glad that our suggestions were helpful. Thank you for posting back to the forum to let us know that you have resolved the problem and that it was issues in the configuration of IP addressing on the interfaces.
