Could someone tell me why the gre tunnel is not working?

[Translator]

I'm writing because there was a problem while setting it up. I don't think the setting itself is difficult, and I think I set it up properly, but it doesn't work. 

Even if I try tracert, it doesn't seem to be using tunnel. 

It's the image of topology and settings. Did I do anything wrong?

Because you config wrong net under each eigrp of both router.

Also you cant use same routing protocol for both, tunnel ip and tunnel source.

Correct network and also use no auto summary.

We have only a little information to work with but not enough for us to understand the issue.As a first step can you tell us if gre1 is able to ping 3.3.3.2? And if gre 2 is able to ping 3.3.2.1?

Hello
Looks like you may be incurring recursive routing, as stated by @MHM Cisco World  the tunnel and source/destination address shouldn’t be advertised with each other, as such the tunnel could see its own source destination addressing through its tunnel, also you are advertising the same network (192.168.1.0/24 from each rtr)

Try the following:

GRE1
router eigrp 100
no network 192.168.1.0
no network 192.168.6.0

ip route 192.168.5.0 255.255.255.0 tunnel 10 

GRE2
router eigrp 100
no network 192.168.1.0
no network 192.168.5.0

ip route 192.168.6.0 255.255.255.0 tunnel 10

Thank you for your reply. As you said, it was a problem caused by an incorrect routing setting and was solved. Have a nice day.

Hello,

if this problem persists, post the zipped Packet Tracer project (.pkt) file...
