[comp.dcom.sys.cisco] NFSNet - MILNET Routing

Hi,

We are connecting to BARRNet soon but we now have a possible
requirement to also connect to MILNET. I would like to use the
following configuration:

             Loral WDL  Ethernet
   __________________________________________
           |              |          |
       ----------    ----------  ----------
       | cisco  |    | cisco  |  | ciscos |
       |  to    |    |   to   |  |to other|
       | BARRNet|    | MILNET |  |Lorals  |
       ----------    ----------  ----------

I would like to know how will the ciscos figure
out what router to send packets to?? Since MILNET charges
by packets now, our customer will not want to pay for our
regular INTERNET data going out over MILNET.

We would like to propose this type of configuration because
I think we would all admit that NSFNet - MILNET connectivity
is real bad. We need reliable connections for our INTERNET traffic
and also for our MILNET requirements.

Has anyone done this ??? Does it work ????

I'm guessing that the "core gateways" on the MILNET would route
data for us over the MILNET connection and that the NSS's on the
NSFNet would route data to us over our BARRNet connection.
How would our network decide which network to send MILNET data to ??
If it was a network 26 destination thats easy but with all the MILNET
backsides with ciscos, I think routing could get confused.

I see that the NIC has what appears to be this type of connection
(according to the latest BARRNet Map).

Any information would be greatly appreciated.
