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.

Subject: Sending RS232 Data over Frame Relay PVC
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,
Kenneth E. Wygand
