Troubleshooting Routing Table

[Jorrie]

Hello, I would like to ask for guidance on how to troubleshoot a routing table. R1 and R7 are unable to update its routing table. I encounter this problem while expanding my network(packet tracer). I'm able to solve the issue at R1's routing table by deleting R1 and R2 routing table using this command "no network 192.168.0.0 0.0.7.255 and adding it back just to make R1's routing table update. Are there other ways how to troubleshoot this kind of problem? and why this problem occurred.

Here are additional information

Routers with their interfaces and IP address

R2 inter gig0/2  IP address is 192.168.0.17/28

R3 inter gig0/2  IP address is 192.168.0.21/28

R4 inter gig0/0  IP address is 192.168.0.18/28

R5 inter gig0/0  IP address is 192.168.0.19/28

R6 inter gig0/0  IP address is 192.168.0.20/28

For routing configuration

router eigrp 1

no auto-summary

network 192.168.0.0 0.0.7.255

passive-interface gigabitEthernet x/x

*note each router has the same routing configuration except for R6.

Hello,

I have rebuilt your network, everything works as expected, compare my settings to yours, you might have missed something.

Working file attached.

Hi. Mr. George I would like to say thank you again for helping me. Unfortunately, the file that you mention I'm unable to open it since it's not compatible with the version that I'm using. Once again thank you and have a great day.

Yours truly

Hello

Thank you for helping me. I start from scratch and reconfigure the IP address and added some devices as you can see in the image so far I don't encounter any problem yet while experimenting with EIGRP but I notice something while configuring EIGRP.

For R3 and R6 their configuration on EIGRP are  autonomous number 1, auto-summary is disabled, passive-interference gig0/0(note* all pc connected to the router are in interface GigabitEthernet0/0), network 192.168.0.0 0.0.0.15 and network 192.168.0.16 0.0.0.15(to establish a connection for network 192.168.0.16, .20, .24.). For R4, and R5 their first 3 configurations are similar with R3 and R6 while for the network it is 192.168.0.16 0.0.0.15 with the said configuration R4 and R5 establish a connection with network 192.168.0.0/28. As for R1, R2, R7, and R8 they also establish a connection with network 192.168.16/30, .20/30, and .24/30 which is quite confusing for my part since I didn't even configure which network they should establish a connection. Can you please explain why does it happen? or Is that the way it should happen? I attached a copy of packet tracer file in this post so that you see all the configurations that I made.

Hello,

I am not sure exactly what you are asking, but when you enter the statement:

network 192.168.0.16 0.0.0.15, that includes all IP addresses from 192.168.0.16 thru 192.168.0.31 (which means all interfaces with an IP address that falls into this range), so these interfaces/networks are being advertised to all clients which are part of the same EIGRP process.

Hence what you are seeing is expected behavior.

By the way, I used version 8 to save the file in. It is usually a good idea to always run the latest version, because it is backwards compatible with all earlier versions.
