Leased line setup Point to Point

[kalale]

Hi,

I setup two cisco router using the following example but I can seem to ping the router from different location

What am i doing wrong or what did i not do?

Do i need to add static routes to the pc or the router?

What is your competency level in Cisco ? (so we know how technical to go)
What ip address of the other router are you trying to ping?
And have you checked the status of the serial on either side?

sh int s0

will show you whether the line is up

im very new to cisco, please go easy on me.

Im trying ping the interface ff0/0 (192.168.1.100) remote office from ff0/0172.16.5.5 (Head office)

 

[Hamish McPanji]

That will not work without routing
You have to work systematically

First check the status of the serial port and line
To do this : show interface serial0

If the port and the line is up, then ping the local serial port (so ping 4.2.4.5 in the example you gave if you are location A)
then ping the remote serial port (so ping 4.2.4.5 in the example you gave if you are location A)

If that is successful, then you can add your routing. How are you accessing the config of the remote site at the moment?

 

[Hamish McPanji]

Yup, not the best idea pasting your configs all over a forum populated by IT people.

Also as far as i know the ip addresses in the range 4.2.4.x are not public, and are assigned to Level 3 Communications in US, so should never be used on a private network

PM me and we can talk privately. And delete the above post

 

[Hamish McPanji]

Please send me a private message, and delete your configurations from above. You have made some basic errors, which i will explain to you on a private message

 

[Hamish McPanji]

I replied you with my contact details. I will help you to sort it out.

I don't recall ever requiring ppp encapsulation for serial links. If you want you can PM me as well.

imranpanji, the 4.2.4.x is from his example, I hope he did not use those...

Yup he did, when I looked at his configs which he posted, I noticed he had used them.

Told him to change it and gave him a private subnet which he could use instead. Am talking to him on email. Will pm you later

PPP is good on serial links,although not required. He got the serial link up, and could ping across,but was struggling to go further

No worries man
We all were novices at some point, the best thing about IT in general is we all help each other

Hi There,
I would be very careful about putting up config details in case an undesirable character decides to hack you.

Glad you got it working and pleased that you are willing to learn

Regards

If it's two routers on a point to point link I can see how that's gonna get hacked bu ja routers connected to the net is a different story.

It was the 4.2.x.x IP address that got me a bit worried. If the company had a public class c address assigned to them then those configs would have given the world a chance to have a good idea of what was behind his firewall(if he has on).

In my previous...hobby as a...unofficial network administrator for quite a few corporate and SME, any piece of information of what is running inside the network is very useful. Finding a cisco config file on an exploitable computer on the network is like gold. It can allow you to map out their network and target your intrusions, rather than doing wholesale portscans which will likely get you caught

The idea is to get in and out as quickly as possible without notice, and leaving some presents behind to let you get back in without a problem. Config files help you minimise you exploration time
