hub and spoke frame relay help

TurK-FX

I am trying to create this hub and spoke frame relay. so i can follow and practice what Chris Bryant does in his videos. But i seem to fail somewhere. Can any1 help me with the commands, so i can compare what i did wrong? I am trying to statically configure to follow his static routing video

Did you already tried to configure this topology?
let me see your configuration

mapletune

yup, if you have any questions dealing with topology and configuration, it's best to just post your lab configs here. It helps us identify what the problem is, and could lead to solving your problem in a more timely manner.

that said, don't post any sensitive information on a public forum... =p

Yes, obviously the first step would be to accurately describe the issue you're experiencing. The second step would be to provide the actual device configurations.

OP> But i seem to fail somewhere.

Imagine you visit your mechanic. When he asks you what's wrong with your car, you say, "But i seem to fail somewhere." What do you imagine he would say?

Here are configs, i am in my ICND1 study, so dont laugh at me pls
I tried as much as my knowledge goes.

Also, i did not put R1`s bolded frame-relay map ip commands, i dont know how they showed up there. I tried to disable them, i put no in front, but it didnt work.

You've given us your car, but still no description of your problem.

I will describe the problems/solutions without providing exact commands--

L2
1. Your hub is speaking frame-relay while your spokes are speaking cHDLC.
2. R2 doesn't know what DLCI to use to reach R3 and vice-versa. This is not necessarily a problem, but has implications for spoke-to-spoke connectivity.
L3
3. R3 is sending packets for 2.2.2.0/24 to R1, but R1 is unaware of that network.

Suggestion:
Learn static routes on an Ethernet topology; learn Frame Relay using dynamic routing; then combine them together. Trying to learn two things you don't understand at the same time makes it harder for you to grasp what's happening or to debug the issues yourself. Good luck, mate.

Here is Chris Bryant's tutorial on Frame Relay -
Frame Relay Switch Configuration For Cisco Lab

Here's a video series on configuring Frame Relay. This is done in Packet Tracer -

thnx bro, i will get on top of that.

I come across to this lab when i was watching the TrainSignal(Chris Bryant`s) ICND1 study, part: Static Routing. I wanted to do what he is doing in the video, but he is kind of start to video in the middle. He already set up that DLCI stuff. I will finish the second part of the video and read the similar chapter on Wendel Odom`s book before i move on.
