Cisco 3640 - X25/VC routing

Hi,

I'm totaly ignorant about routers configuration/possibilities.

I'm using a 3640 router to reach my clients.

My software uses X25 with PVC and SVC connections.

I'm wondering if it is possible to do VC routing , i.e :

- my client is connected to my router and he uses CV 10 for sending/receiving data.

- my software, needs to use the CV1 (between my machine and the router)for transmission and CV 2 (between my machine and the router) for reception

I want the router to do the following :

received data from my client on CV 10 will be routed on my CV 2

Data my software writes on CV1 will be routed to CV 10

Is this possible with this kind of router ?

Thanks a lot.

Re: Cisco 3640 - X25/VC routing

Yes, it is possible to do what you want. It uses several serial interfaces however, but it's possible. Your configuration would be similar to the following;

interface Serial0

description WAN link to customer CV10

no ip address

encapsulation x25

bandwidth 56

x25 ltc 100

x25 accept-reverse

x25 pvc 1 interface Serial1 pvc 1

x25 pvc 2 interface Serial2 pvc 2

!

interface Serial1

description CV1

no ip address

encapsulation x25 dce

x25 ltc 100

x25 accept-reverse

x25 pvc 2 interface Serial0 pvc 2

clockrate 56000

!

interface Serial2

description CV2

no ip address

encapsulation x25 dce

x25 ltc 100

x25 accept-reverse

x25 pvc 3 interface Serial0 pvc 3

clockrate 56000

Be sure to change your in/out window size and your in/out packet size to match your application, using x25 wins # and x25 wout #, x25 ips # and x25 ops #. There are other x25 parameters that can be set, those above are just the basics to get it up and working. I am not an expert nor do I claim this to work for you, it did for me.

The following link on Cisco's site shows a simple interface to interface configuration. The above should work for you to allow you to split the xmit and recv to different interfaces.
