Help with my lab

boekholtj

I bought some lab equipment on ebay to help me study for my CCENT/CCNA exams.
I bought 2 2611 routers. They each have 1 ethernet 1 token ring and 2 serial ports. I also have 2 2950 switches. The 2 routers are connected by a smart cable via serial port s0/0.

I'm trying to setup routing. I've tried using static routes and rip. I'm unsure why it isn't working. Can someone look at my startup configs for my 2 routers and see if they see my mistake?

R1 connects to the network, R2 to my internet router (10.0.1.1). I can ping all devices/address from R2, but can not ping the internet router from R1. I usually get no response. Sometimes I'll get a U response from ping.

Are you trying to NAT between your ethernet/serial interface?

I'm trying to make it work. I'm not sure that the hardware even works. I dont know how to properly troubleshoot the problem, so I cant rule anything out. I'm pretty sure its misconfigured. I just don't know what I am doing wrong. If NAT is required, how would I configure NAT correctly?

Roguetadhg

If you're unsure the hardware works. Disconnect it from the internet. Make it works without, first.

MosGuy

I agree with Roguetadhg. If you're unsure that the hardware works it's better to start simple. I would likely erase things & start over. Get everything working on the local LAN before trying to add NAT/Internet. If I was trouble-shooting the current setup. I would remove NAT & debug the RIP process to ensure announcements were being sent/received. I did note that on router 1 it's advertising the 1.x network. On router 2 there are two entries on the serial link. One being a static route. I'd remove the static, since they should be learned through RIP if all is working properly.

When in doubt wipe everything and take it one step at a time. Verifying things work before adding the next piece. Doing too much at once makes trouble shooting trickier.

Thanks guys!

I took your advice and erased my startup-config on all my devices. I followed the RIP lab and was able to setup both RIP and Static routing. I can rule out hardware as a problem now.

Now I would like to set up the stub network I was trying. What do I have to do different when I introduce the internet?

A few thoughts about your problem:


- If you're trying to learn about NAT and for that reason insist on doing NAT on every network great, but to start off with, why not keep things simple and disable NAT everywhere, except of course on your home Internet router? Since all the networks are official reserved IP networks, you don't need to use NAT between them, you should be able to route instead.

- The logical way to troubleshoot this problem is to take it step-by-step: From your PC, can you ping 192.168.1.254, R1's Ethernet interface which you're presumably connected to? (Don't forget to double check that you have the correct IP on your PC setup as the default gateway) If so, how about pinging 192.168.2.1, R1's serial which connects to R2? If yes, try pinging R2's serial interface, then R2's ethernet interface which connects to your router. Finally, try pinging 10.0.1.1, your internet router. One of these steps might fail. If each test was successful, start implementing NAT, one network at a time.

lantech

I would get things working 1 at a time.

Get the network setup and then work on getting them connected to your internet router.

When your setting up your network get things working one at a time as well. That way if something isn't working correctly you can probably rule out something else right away. For example, get routing working between the two 2611s then maybe set up NAT. That way if NAT isn't working you can probably rule out routing right away because you know your routing is working.

What is the purpose of connecting your network to the internet?
