Cisco packet tracer 6 / How to connect 3 Multilayer switchs

[lmouktassidkhaliil1]

I wan't to ping from "PC" in the right (DIRECTION FES) to  PC in the left (DIRECTION KENITRA) but when I ping it fail , I tried to connect "Multilayer Switch3" and "Multilayer Switch0" but I failed , I used the next commands : 

Multilayer Switch3(config)# router rip

Multilayer Switch3(config)#network 10.0.0.0

Multilayer Switch3(config)#network 192.168.30.0

and

Multilayer Switch3(config)# router eigrp 1000

Multilayer Switch3(config)#network 10.0.0.0

Multilayer Switch3(config)#network 192.168.30.0

but without any effect.

Please help me to ping succefuly and connect all the networks succefuly.

Pick one routing protocol. I would use EIGRP because RIP is classful and you have major networks separated by other major networks.

On each L3 switch configure EIGRP and include network statements for the attached subnets.

Add "no auto-summary" under the EIGRP configuration. If you add it and it doesn't show up that's fine it just means it is the default.

Thanks Jon for replying , I just did what you told me and did not work :-(

I can't find the problem ... could you tell me how to configure major networks separated by other major networks using multilayer switchs ?

Thank you very much.

It looks like you have 4 L3 switches in your topology.

In addition it's not clear which subnet is being used to link the middle two switches. I have assumed 10.0.0.0/24.

So remove any existing RIP or EIGRP configuration and from left to right on your diagram in terms of switches add this -

left switch
===============

router eigrp 10
network 13.0.0.0 0.0.0.255
network 192.168.30.0 0.0.0.255
no auto-summary

middle left switch
==================

router eigrp 10
network 10.0.0.0 0.0.0.255
network 13.0.0.0 0.0.0.255
no auto-summary

middle right switch
===================

router eigrp 10
network 10.0.0.0 0.0.0.255
network 12.0.0.0 0.0.0.255
no auto-summary

right switch
===================

router eigrp 10
network 12.0.0.0 0.0.0.255
network 192.168.10.0 0.0.0.255
no auto-summary

try that out.

When you add these commands you should see EIGRP neighbors coming up. To check -

"sh ip eigrp neighbors"

see if it works and if it doesn't come back.

If it does and you want an explanation then please come back as well.

I did a new project and configure from the first , and when I used your commands I have this result : 

sw# IP-EIGRP neighbors for process 10

sw#

I don't know why ?

I have some questions ? can I use trunk mode on the middle but I just know how to configure the 802.1Q and set the trunk mode , sould it pass the ping ? and I am using "SVI" and "routed port" now to connect inter-switchs  :

Switch2(config-if)#

is that good ?

thank you very much

Please post the configurations of all four switches.

Add them as attachments to the post.

And please indicate which configuration is for which switch in your diagram.

That's all the configuration that I did now ...

please , could I show you my complete project ? 

Thank you again

You need to look at your switch configurations and go through them carefully.

Just looking at them I can see the EIGRP configurations are wrong.

On each switch you should only have network statements for connected networks, not for networks that are not directly connected.

If you go through them again and reference your diagram you should be able to see that you have configured network statements under EIGRP for networks that are connected to other switches.

That is why EIGRP is not coming up.

Yeah absolutly right , It helped me.

This is my Full project : 

I just have to add some PCs on the green and pink (left) ones.

- I have to do all the pings successfully 

- Pass all the calls 

- and connect all the servers rightly 

and DHCP and vLANs ...

Hello Khalil,

Can you please send me your topology config?

Thank you.

Hello Khalil,

  I am studying Network as a student from Myanmar. I want to learning about your topology config. Can you please send me your topology config?

Thank you.
