How to create route via many routers?

Hi, I'm learning routing now and I have to do a task, but I don't know how to connect some routes- could you help me?
This is the situation: (Netz(werk) = net(work) in German)

Every pinging works fine, but only pinging from the right to left and from left to right networks don't work- I tried everything possible for me- I know how to create routes between routers and networks and I know how to set default routes- but everyhting I tried to do, didn't worked- how would you solve the problem, so the ping from PC4 could reach for example pc3?

 

Any ideas would be really helpful

Hello,

 

I opened your file, and the problem seems to be that you simply configured the wrong interfaces with the wrong IP addresses. On Router1:

 

interface Serial0/0/0
ip address 172.16.0.21 255.255.255.252
clock rate 2000000
!
interface Serial0/0/1
ip address 172.16.0.25 255.255.255.252

 

needs to be:

 

interface Serial0/0/0
ip address 172.16.0.25 255.255.255.252
clock rate 2000000
!
interface Serial0/0/1
ip address 172.16.0.21 255.255.255.252

 

Attached the revised, working file.

Hi,

The ping is 2 ways, you send a request and you should receive an answer, now the case is weird and it could be associate to a bug in PT, check the routing section and you could share your PT file to verify.

 

Regards.

I don't know, why router1 doesn't want to communicate or route to router0 or router2

thank you SO MUCH !!!! I think, I wouldn't be able to find this mistake that fast! As you see the screenshots, packet tracer is showing it really bad and... thank you so much! Really, I'm learning routing now and I thought this will be some frustrating stuff again- thanks anyway, if karma exists, I send much to your account! Really, thanks for your time- help like that cannot be taken for granted
