I have an x25 call established between two peers through PAD over XOT. Assuming that i would want a packet transfer to be exchanged between both these peers (two end hosts connected to routers). Can i achieve this through regular ftp?

Hello echelon,

Maybe what you need is X.25 and TCP/IP combination. I don't know if you are already using it. But, you can use the x25 link to pass your ftp traffic. Try this.


int s0

enc x25

x25 address 123456

x25 map ip 654321

ip address


ip route R2-SUBNET


int s0

enc x25

x25 address 654321

x25 map ip 123456

ip address


ip route R1-SUBNET

thank you for replying!

I have attached a diagram of what i'm trying to achieve.

Essentially, i would like to have X25 calls generated between WAN POP A and WAN POP B. Once that is verified working. I would like to have WAN POP B migrate to Core 2. This will help me validate impacts on X25 during migration.

I was hoping to accomplish this by first,setting up an FTP transfer between both X25 PEERs and have that running. Once that is active, i will initiate the migration.

Hi echelon,

I didn't understand the relation between the FTP and the X25 migratration. Can you provide more details?

thank you for taking the time to reply.

What i was hoping to achieve was

1) ensure an x25 call is active between both peers (i.e WAN POP A and B)

2) Ensure that there is packet transfer between both peers.

3) initiate the migration at the core end to see the effects it has on the x25 call/packet transfer

I will have two linux hosts plugged in at the endpoints of both the WAN POP Routers to ensure the packet transfer over X25.

I will have to run the same test again but this time, over an asynchronous serial interface and evaluate the impacts.

Any thoughts on this pls?
