Hi,

There are no issues with the configuration from my observation.

Firstly, where are you telnetting from? I.e. is it from the other router, or from somewhere else on the network?

Also, what exactly happens when you try to telnet to the router? Does it just time out, or do you get a "connection refused"?

The only other possibility is that all the vty lines are used up and the router won't allow anyone else in. You will get a "connection refused" error if this is the case.

Hope this helps,

Michael.

Hi Mahesh,

To get a login prompt what you have stated is correct.

However, if you want to enter privileged exec mode (enable mode), then you will also need the lines:

enable secret 0 password

or

enable password 0 password

You cannot enter privileged exec mode through a telnet session unless you have a enable password set.

You should also confirm that there are no access-lists applied to the VTY line. You will see this if there is a line starting with "access-class" under the vty 0 4 section. This would stop you from getting into the router but still able to ping it.

Hope this helps,

Michael.

Hi Mahesh,

1) Check if you have any outbound acccess list in your end serial interface.

2) Check if you have any inbound access list specified in the serial interface on the other end router. Any possible to get console access to the other end router to check this ?

do you get any error message when you telnet to the other end ip address from your router ?

Hi Mahesh,

I noticed your IP addressing is different in your configuration as to what you originally posted. Is this intended?

Your IP in the config is 59.145.165.89 and .90

But in your original post it's:

59.145.165.125 and .126

Your config looks OK otherwise.

Thanks,

Michael.

that was by mistake ip is configured as per my previous post which is 59.145.165.125/30

but is there any other issue n configuration

Pl. revert
