Cannot ping between routers

[ITgrad]

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:

Any help/guidence is greatly appreciated

[Richard Burts]

There are multiple things in these configs that need to be addressed.

- your first router is configured for OSPF but not your second or third router. dynamic routing would be one way to establish connectivity between these networks. But if you want to use dynamic routing then it needs to be configured on all three routers.

- your comment suggests that the point of this configuration is about static routes. If that is the case then why is dynamic routing configured on one router?

- the static default route on each of the 3 routers is not correct. You have

ip route 0.0.0.0 0.0.0.0 0.0.0.0

what is not correct is that you are specifying 0.0.0.0 as the next hop address. You need to specify an appropriate IP address that is connected to the router.

- you have configured the serial interfaces but we can not determine what state the interfaces are in. Can you post the output of the command show ip interface brief from each of the routers. It might also be helpful if you post the output of the command show cdp neighbor from each of the routers.

- one of the serial links is configured to use ppp and to authenticate with chap. But I do not see the parameters that would allow chap authentication to be successful.

- the first router is configured with access-class on the vty. But the access list specified for the access-class is not in the config.

Appologies on not including all the required information, I am new to forum posting for guidence. Your reply is greatly appreciated! 

OSPF is enabled on ACMER1 because it was me just trying to get it to work initially, but then not removing it after it failed to work. The default route was also me just trying something to see if it'd work. I know this is not the way to troubleshoot, but I've been tearing my hair out to at this point. Bellow is the task I am currently on in my assignment: 

"

Task 3: Configure Routing

You should be using as few static routes as possible in this assignment, any unnecessary static routes (e.g. because of an incorrectly configured routing protocol) will cause a loss of some marks.

- You are to assume that ACME, OtherISP and ISP are all separate autonomous systems that are part of the Internet and that there may be many more autonomous systems connected to ISP and OtherISP that are not shown.

- Configure OSPF and BGP in the appropriate places based on the correct use of interior and external gateway protocols. The Autonomous System (AS) numbers are given to you in the separate web page (each student has unique AS numbers).

- Configure appropriate default and static routes (keeping these to the absolute minimum). Default route(s) should be distributed appropriately. 

- Note that dynamic routing does not currently work across GRE so you should only use static routes inside the SOHO network (and to the SOHO network). You should note that, at this stage, you should have internal connectivity inside the ACME network, but only connectivity to Internet systems using public source addresses (e.g. from the ACMEWebServer). Other connectivity depends upon NAT and the GRE tunnel."

"cdp is not enabled" on all three routers

Bellow is the "show ip brief" result on all three routers:

ACMER1

[Richard Burts]

Thanks for the additional information. Based on this I believe that your attempt to configure OSPF was the direction in which you need to focus. And what was in your original post for the first router was a reasonable start. You would want similar configurations on both other routers. This would provide connectivity between the networks in this AS.

The biggest reason that things are not working at this point is some issue with configuration of the serial interfaces. As you can see in this output

Serial0/0/0 172.16.1.153 YES manual up down

Serial0/0/1 172.16.0.73 YES manual up down

So you need to figure out why these interfaces are line protocol down.

The good news is that one of your serial interfaces is up/up

Serial0/0/1 172.16.2.73 YES manual up up

Hi @ITgrad

 Let me help you in some config:

On router ACMER1 you create dynamic routing and one static route, but, the static route is incorrect:

ip route 0.0.0.0 0.0.0.0 0.0.0.0

the correct should be:

ip route 0.0.0.0 0.0.0.0 172.16.0.74

Router ACMER2 know both route so they dont need static route.

On router ACMER3, you didn't create any routing statement, but you should have:

ip route 0.0.0.0 0.0.0.0 0.0.0.0 172.16.2.73

This way, you should be able to ping among routers. 

Try this and let me know. If possible, attach you pkt file below. You need to rename it to txt file otherwise you can´t attach.

-If I helped you somehow, please, rate it as useful.-

[ITgrad]

pkt file has been attched further down the page

[Georg Pauwen]

Hello,

in addition to Richard's post...can you post the .pkt file ? You need to rename it to .jpg first, otherwise you cannot upload...

[ITgrad]

the packet tracer file

[Flavio Miranda]

Try to add dynamic and static route as required and test again, this should work. If you fail, then, let me know.

-If I helped you somehow, please, rate it as useful.-

[ITgrad]

I've tried adding the dynamic and static routes, but it keeps telling me "line up, protocol down" when I try ospf, and the static routes simply don't work

[Georg Pauwen]

Which version of Packet Tracer are you using ? I cannot open this in 6.2, 6.3, 7.0, or 7.1.

[Saurabh Gera]

Please decide which way you want to go 

1. Static Routing 

2. Dynamic Routing 

3. Mixed Environment. 

1. Static Routing, You might want to point default to other router if want to use static. 

ip route 0.0.0.0 0.0.0.0 a.b.c.d ( Replace this with 0.0.0.0 and put other router's IP address )

Its better to give more specific routes instead of 0.0.0.0, if you know the networks on other side ( unless you want to send traffic to internet ) 

2. Dynamic Routing :- Please do similar config of Router 2 and Router 3 ( as its done on router 1 ) .

3 Mixed Routing :- Please configure two with dynamic and point a default of third one to any of the dynamically configured Router. 

[ITgrad]

I am required to set up a varition of a static route(s), and then implement ospf across the ACMER routers 

[Flavio Miranda]

You can do dynamic routing between 1 and 2 and static between 2 and 3.

 Just setup OSPF on 2 and static on 3 and you are good.

 You're going to decide out that OSPF on serial link may require some additional commands but as you're leaning, this is nice for you.

-If I helped you somehow, please, rate it as useful.-

[ITgrad]

when I setup ospf, the interface is "line up/ protocol down (disabled)"
This is an issue that I ran into before; when I implement ospf on any lf the three routers it says the protocol is down on the interface I add to opsf
