RE: Sending RS232 Data over Frame Relay PVC

Tim & The Group,
 
One last question for you. Can you send the serial stream to a loopback IP address as the destination and then that router will send the serial data out based on the serial interface being part of the stun group?
 
For example, if I am trying to tunnel a 56K connection from Serial0 on R1 and Serial0 on R2, and R1 and R2 have two different frame relay links between them (for redundancy) and thus different destination IP addresses, can I just target the 56K connection toward the loopback interface of the remote router and visa versa?
 
Is this how you did it?
 
Thanks,
Ken

        Kenneth,
        
        I have used STUN for proprietary protocols that are not IBM SDLC. It
        basically just takes the frames off the interface and encapsulates them and
        sends them to the other side of the STUN connection.
        
        Here is a basic config:
        
        Router #1
        
        stun peer-name xx.xx.xx.xx
        stun protocol-group 1 basic
        
        interface Serial2/2
        encapsulation stun
        nrzi-encoding
        clockrate 19200
        stun group 1
        stun route all tcp yy.yy.yy.yy
        
        
        Router #2
        
        stun peer-name yy.yy.yy.yy
        stun protocol-group 1 basic
        
        interface Serial0/0
        encapsulation stun
        nrzi-encoding
        clockrate 19200
        stun group 1
        stun route all tcp xx.xx.xx.xx
        
        The only problem with this is that it is one to one mapping. Not 1 to 20.

        Thanks again for the info Charles.
        
        I've been looking up the STUN technology on cisco.com but I haven't had much
        luck finding much information on the technology itself and how it works,
        etc. (to determine if it will work for my application).
        
        I found a lot of configuration examples as well as a F.A.Q. page, but
        nothing that discusses the technology in general.
        
        Any advice?

        Kenneth,
        
                Check out STUN (serial tunnelling). It can encapsulate serial data
        into IP. I've used it to handle SNA out of older ATM (bank machines) back
        to a central site.

        Elite Team,
        
        
        
        I have a hub-and-spoke Frame relay network I am looking to implement - 20
        spokes and 1 hub with Frame Relay connections from the hub to each remote
        site. I also have a 56K synchronous serial RS232 line I must transport over
        this frame-relay connection from the hub to each of the remote sites
        (proprietary application). ALL REMOTE SITES RECEIVE THE SAME INFORMATION
        FROM THE HUB!
        
        
        
        Is there a way I can do this within a Cisco box? Would the DLCI
        configuration be able to support these requirements? I'd like to only send
        one copy of the feed into the Cisco router (thus requiring only one serial
        connection) and then copy it 20 times. Cisco said this can be done within
        the frame relay DLCI configuration, but I am not so sure. I'm assuming that
        with this method, I'll still need to use 20 x 56K bandwidth on the frame
        relay link connected to my hub and that's not really a big deal to me. I
        just don't want to have to have 20 serial interfaces on the Cisco Router to
        pump each individual feed (copied 20x) to each remote site.
        
        
        
        IP traffic will have to cross the link as well for Internet Access purposes.
        CIR at each remote site will probably be about 256K, including the 56K
        synchronous serial connection being carried over this link.
        
        
        
        Any suggestions or advice would be greatly appreciated.
        
        
        
        Thanks,
