I have a (perhaps naive) question about the interoperability of routers:
We want to join Ethernet LANs in two different cities with a 56kbps sync
line.  The LANs run a variety of protocols such as XNS, TCP/IP, Decnet.
We want to use routers at each end of the line.  Do the two routers
have to be from the same manufacturer?  If so, why?  One of the routers
is a Cisco box but the other could be Proteon or some other make
(or does it have to be a Cisco?).
