Packet Tracert Excercise with RIPv2

kwanbisCCNA — Fri, 08 Mar 2019 10:48:19 GMT

Hello everybody. I have started learning VLSM and RIPv2. I have 3 routers, 4, lans, etc. You can see the topology on the file.

I have connected the reouters through their 0-0, 1-0 and 1-1 (last to first) serial ports.

And I have configured the routers like this:

R0:

000: 192.168.0.193 255.255.255.252
001: 192.168.0.202 255.255.255.252
ETH: 192.168.0.1 255.255.255.128

R1:

000: 192.168.0.194 255.255.255.252
001: 192.168.0.197 255.255.255.252
ET1: 192.168.0.129 255.255.255.224
ET2: 192.168.0.205 255.255.255.252

R2:

000: 192.168.0.198 255.255.255.252
001: 192.168.0.201 255.255.255.252
ETH: 192.168.0.161 255.255.255.224

For router 0 y executed on RIP mode on the CLI:
version 2
network 192.168.0.193
network 192.168.0.202
network 192.168.0.1
(I understand that I can just execute: network 192.168.0.0, is that so?)

For router 1 y executed on RIP mode on the CLI:
version 2
network 192.168.0.194
network 192.168.0.197
network 192.168.0.129
network 192.168.0.205

For router 2 y executed on RIP mode on the CLI:
version 2
network 192.168.0.198
network 192.168.0.201
network 192.168.0.161

The IP, Mask, Gatway of the PCs are:
PC0 192.168.0.2 255.255.255.128 192.168.0.1
PC1 192.168.0.3 255.255.255.128 192.168.0.1

PC2 192.168.0.130 255.255.255.224 192.168.0.129
PC3 192.168.0.131 255.255.255.224 192.168.0.129

PC4 192.168.0.206 255.255.255.252 192.168.0.205

PC5 192.168.0.162 255.255.255.224 192.168.0.161

If I ping from PC0 to the others,
ping 192.168.0.2 OK (itself)
ping 192.168.0.3 OK
ping 192.168.0.130 x (dies on router 1)
ping 192.168.0.131 x (dies on router 1)
ping 192.168.0.206 x (dies on router 1)
ping 192.168.0.162 ok

Any idea why is not working?

THANKS!

Hello,

Please share your configuration in text format.

setting network 192.168.0.0 is fine.

Try to set no auto-summary under RIB configuration and test the result.

Thansk for replying. How do I

Thansk for replying.

How do I share it in text format? Like so?

You mean this?

Router(config)#router rip

Router(config-router)#no auto-summary

Router(config-router)#

On all 3 routers?

I just did that and it did not work.

Thanks!

Hello,

Masoud Pourshabanian — Sun, 22 Nov 2015 19:53:12 GMT

Hello,

Copy pasye all 3 configurations in a text file with specifing the name of the routers. Then attach the text file.

Masoud

I'm sorry, I'm just to new to

kwanbisCCNA — Sun, 22 Nov 2015 20:16:59 GMT

I'm sorry, I'm just to new to PT and I'm not sure how do you want me to copy the configurations if you mean from the PT itself. If you mean what configuration's I'm using, it is this:

Router 0 is connected through serial 000 to serial 000 of Router 1. Router one is connected though serial 001 to serial 000 of Router 2. Router 2 is connected through serial 001 to serial 001 of Router 0.

Router 0:
Serial 000: 192.168.0.193 255.255.255.252
Serial 001: 192.168.0.202 255.255.255.252
Ethernt 00: 192.168.0.1 255.255.255.128

PC0 and PC1 are behind a switch that is part of Router 0's network.

PC0
IP: 192.168.0.2
Mask: 255.255.255.128
Gatway: 192.168.0.1

PC1
IP: 192.168.0.3
Mask: 255.255.255.128
Gatway: 192.168.0.1

Router 1:

Serial 000: 192.168.0.194 255.255.255.252
Serial 001: 192.168.0.197 255.255.255.252
Ethernt 00: 192.168.0.129 255.255.255.224
Ethernt 01: 192.168.0.205 255.255.255.252

PC2
IP: 192.168.0.130
Mask: 255.255.255.224
Gatway: 192.168.0.129

PC3
IP: 192.168.0.131
Mask: 255.255.255.224
Gatway: 192.168.0.129

PC2 and PC3 are on the same switch, PC4 is in another switch, both switches are part of Router 1's network.

PC4
IP: 192.168.0.206
Mask: 255.255.255.252
Gatway: 192.168.0.205

Router 2:
Serial 000: 192.168.0.198 255.255.255.252
Serial 001: 192.168.0.201 255.255.255.252
Ethernt 01: 192.168.0.161 255.255.255.224

PC5 is directly connected to Router 2.

PC5
IP: 192.168.0.162
Mask: 255.255.255.224
Gatway: 192.168.0.161

By the way, I uploaded the PKT file on the 1st post.

PKT version is not compatible

Masoud Pourshabanian — Sun, 22 Nov 2015 20:20:46 GMT

PKT version is not compatible with my packet tracer version.

For example go on R1 and Show running config. Copy whole configuration and paste it to a text file. repeat on R2 and R3.

Masoud

I understand now. I just

kwanbisCCNA — Sun, 22 Nov 2015 20:30:42 GMT

I understand now. I just uploaded all 3 configs inside a ZIP. By the way, I'm using version 6.2.

Confuguration looks good;

Masoud Pourshabanian — Sun, 22 Nov 2015 20:45:31 GMT

Confuguration looks good; however, I do not see "no autosummarization command". I am trying to update my packet tracer to 6.2.

Just make sure you can ping IP addresses of serial interfaces from other routers.

I will get back to you.

Masoud

Thanks a lot for your help.

kwanbisCCNA — Sun, 22 Nov 2015 21:07:25 GMT

Thanks a lot for your help. Be waiting.

Hello,

Masoud Pourshabanian — Sun, 22 Nov 2015 21:09:55 GMT

Hello,

I checked the configuration. The IP addresses on router1 are wrong. you need to replace IP address G0/0 with G0/1

interface GigabitEthernet0/0
ip address 192.168.0.205 255.255.255.252
duplex auto
speed auto
!
interface GigabitEthernet0/1
no ip address
ip address 192.168.0.129 255.255.255.224
duplex auto
speed auto

Masoud

I'm sorry, but I don't

kwanbisCCNA — Sun, 22 Nov 2015 21:22:40 GMT

I'm sorry, but I don't understand your solution.

CURRENTLY

GigabitEthernet0/0
192.168.0.129 255.255.255.224

GigabitEthernet0/1
192.168.0.205 255.255.255.252

"SOLUTION"

GigabitEthernet0/0
192.168.0.205 255.255.255.252

GigabitEthernet0/1
192.168.0.129 255.255.255.224

So basically we are just switching the IPs. Why would that work? (I'm changing the config as I write this).

I just uploaded the topology just in case.

Because PC2 and PC3 are

Masoud Pourshabanian — Sun, 22 Nov 2015 21:29:53 GMT

Because PC2 and PC3 are connected to switch3 and switch3 are connected to R1 G0/1.

PC2 ip address is 192.168.0.130 while interface G0/1 ip is currently is 192.168.0.205. They are in the same range. You need to put 192.168.0.129 on G0/1 because 192.168.0.130 and 192.168.0.129 are in the same page.

Replace the IPs and try to ping again.

Masoud

So the problem is that I

kwanbisCCNA — Sun, 22 Nov 2015 21:31:47 GMT

So the problem is that I configured por A for Network X but then the PCs wrong? How can you know which port is connecting to any switch?

Go to option, preference, you

Masoud Pourshabanian — Sun, 22 Nov 2015 21:36:52 GMT

Go to option, preference, you see an option.

"Always show port labels"

You will see the port labels on your topology.

Another way is keeping mouse on the link( just keeping ,not clicking). interfaces name will be shown.

Masoud

Thanks a lot for all your

kwanbisCCNA — Sun, 22 Nov 2015 21:46:02 GMT

Thanks a lot for all your help. I was getting crazy 😉

Glad to help. Masoud
