Is on by default.

Could anyone have a look at this and tell me if it looks ok? cant get it to work on packet tracer

Welcome to TE...

What's not working? By looking at your config and your diagram, I will tell you... you need PPP enabled on both routers that's connected via PPP. I see you have one end setup for PPP, but you would need the other end of the PPP. Second, the same rule applies for your Frame Relay... you can have it enabled on one router, but if all other routers aren't configured for Frame Relay then you will not be able to communicate via Frame Relay... As you mentioned... HDLC is enabled by default... so without seeing your configs, I'm not sure what's working or what's not working... Can you post a running config for each router and then tell us what you're having problems getting to work? HTH

In addition looks like your using Packet Tracer, the only way Frame-relay will work probably in Packet Tracer, is you have to implement a WAN cloud in between the two devices, then you have to click on the cloud and configure frame-relay with the proper DLCI's.

Too much is missing from the op's post, like a cloud, dlci's and ip's. Need more info.

I agree. Can you show us the entire configs, because it honestly looks like there have just been a few devices thrown up, with not much done to them. Plus your diagram shows the links as red, meaning they are down/disabled. Did you even enable the interfaces on all sides on each router? If so, they should be green in PT.

I've got same problem. These are all the information i have. And my configuration that dont works in frame relay and hdlc

My configuration in PT is the next, but i can´t ping from R3 to R2 (HDLC) and R2 to R1 (Frame Relay)

What exactly is not working? What can communicate and what can not? It's to early here for me to cycle through running configs for a needle in a haystack.

mikej412

If this is your homework it kind of defeats the purpose if you ask us rather than your instructor.

If the HDLC isn't working between R2 and R3 -- what does show ip int brief show on for those interfaces? What do you want it to show? If that looks good but they still can't ping each other, are they on the same network (are the IP addresses and subnet mask correct)?

What's that table? The current configurations? Are the configurations on the Diagram the ones to be considered correct?

And if you post configurations, use code blocks and tell us which device they are for outside of the code block -- I don't have time to scan a blob of code and hunt for host names and page up and down looking for individual configurations.

frame relay in packet tracer...??? to use FR you need one of those clouds is a mess...my advice practice FR in GNS3 is much easier understand there

JaCkNiFe

mastropiero: Your problem between R2 and R3 is the subnet.

R2 = S0/0/1 172.16.0.5 /30
The range of addresses here is
172.16.0.4 subnet
172.16.0.5 and .6 host addresses
with a broadcast address of 172.16.0.7

R3 = S0/0/1 172.16.0.10 /30
The range of addresses here is
172.16.0.8 subnet
172.16.0.9 and .10 host addresses
with a broadcast address of 172.16.0.11

Take a look at ALL your links and apply your sub-netting skills, I am sure you can get it fixed up.

As for R2 to R1 when you use CHAP authentication you have to have a
"username (neighbor routers hostname on the other end of the point to point link) password (password)"
placed on both routers with a matching password to authenticate.

Thank you very much JaCkNiFe.
I spent lot of time and i couldn't see the problem because i believe all data whitch was given to me were ok. Now all is working perfectly.
One million of thanks. I hope I can return the favor.
Thank very much again.
Best regards.

You need the frame-relay switch between R1 and R3 and you need to make both of them DTE devices (ie no "clock rate" command) on both serial lines connecting to the cloud.

Here's what mine looks like:
