OSPF 4 router configuration problems in Packet Tracer

[pmtp94]

Hello,

I'm currently working on an exercise in Packet Tracer with the following layout:

I've connected the 4 routers via serial and created 4 different networks between them.

I've also configured OSPF the following way:

The network works fine this way, the problems begin when I start removing connections for testing.

For example:

.If network 192.168.3.0 goes down, Router01 can't reach network 192.168.4.0

.If network 192.168.6.0 goes down, Router01 can't reach network 192.168.5.0

.If network 192.168.4.0 goes down, Router02 can't reach network 192.168.3.0

.If network 192.168.5.0 goes down, Router02 can't reach network 192.168.6.0

Is this normal behavior? and is there any solution to this problem? can I make this network work even if any of the inter Router networks go down?

Sorry if there is any lack of information, I'll post more if necessary. I've also included the project file if you want to check it out.

Thank you,

Pedro

Well then,

Thank you very much for your help.

I'm doing this exercise for my internship. Since it works, I'll talk to my superiors about the issue.

Thank you,

Pedro
