Frame-Relay wrong!

Hallo

Everything I entered in the cloud was not accepted as correct. I don't know where the problem is.

Thank you in advance

Take a look on this video, it might help you.

Have you done an Internet search for something like "frame relay configuration in packet tracer". It should return lots of examples.

What's the source of your configuration? I ask because I recall using subinterfaces with DLCI assignments. That's not to say your using frame-relay maps is incorrect, in principle, although disabling inverse ARP might be required.

Later today, I may have time to load your PT file.

Joseph W. Doherty — Thu, 09 Apr 2026 12:06:12 GMT

BTW, although I assumed your topology was ptp, possibly not as I see all 3 routers are using FR IPs in the same subnet, 10.0.0.0/8. I guess I really need to see your PT file for the actual topology. I also see two routers Ethernet interfaces in the same subnet 172.16.0.0/16.

Hi Flavio

Thanks for your URL. I have already watched this one:

https://youtu.be/JpUveApljiw?si=NhY8faDIRzW4jH6c

It is whit only one Subnet and no point to point.

I did it 1 to 1 from Video, but is not going well.

Hi Joseph

Thanks for your words.

I will change the subnet

Hello all

It is now OK and every PC can connect other.

My mistake was cloud setup and I looked at Video from Flavio and correct my cloud.

Thanks once again for your support

Joseph W. Doherty — Thu, 09 Apr 2026 18:05:06 GMT

Yep, when I finally got a chance to load your original file, the FR cloud wasn't configured correctly. (I'm not positive it's actually correctly configured as is - much depends on what kind of logical topology you're creating, full mesh or hub and spoke.)

Your revision still has 176.16.0.0/16 on two routers' LAN interfaces. That needs fixing.

You're using a /8 network for 3 IPs is perhaps just a bit wasteful of IP address space; probably using the /16 for a LAN subnet is somewhat wasteful too. As you're running original RIP, suggest you use Class C networks.

Hi Joseph
You are right and the topology could be a bit better and IP addresses should be 30-bit. But for all the first tests I just used everything simply, even router RIP! And I changed the second subnet whit 172.16.0.0:-)
But I will try to do better soon!

Thanks a lot

Re: Frame-Relay wrong!

Joseph W. Doherty — Thu, 09 Apr 2026 18:11:19 GMT

BTW, as to using /30 networks, you cannot on the WAN, as you have 3 devices in the subnet. You could with your LANs, but if you continue to use RIP, it's classful, so you need to use, minimally, a /24.

Hello guys, Hello Joseph!

In Packet Tracer I couldn't create a serial sub-interface, so I configured two serial interfaces on R1. In my Frame-Relay, R1 and R2 have no contact, whereas it works for R1 and R3. I don't know what I should change?

Thanks in advance

Hello everyone I changed the cloud settings and connection from all levels goes smoothly. Thank you
