That sounds like an interesting solution. I've never routed/bridged
DECnet in that way.
It's no different than any other DECnet routing. And it's technically
routing we're talking about, and not bridging. Any machine with more
than one circuit active at the same time by definition is a router. If
you configure a machine as an end-node it can only have one active circuit.
The KMC/DUP speaks "DDCMP" that is not
spoken by a cisco router sync
interface.
You need for example to run the sync line from the 2020 to a LSI-11
with
RSX (as you can get help from Johnny with rsx..) and a sync and
Ethernet
interface in the 11. (Or any PDP11/VAX with a sync interface.)
(I'm an old hand at RSX)
So we could use a PDP-11 with a KMC11 to bridge DECnet over DDCMP
to Ethernet? Of course another interesting option would be for
pyDECnet to
implement DDCMP, and let some random RPi or virtual machine bridge the
KS' DECnet to the rest of the world.
Yeah. Not sure if PyDECnet have DDCMP yet, but of course, that could be
implemented.
And then it's the same story there. Packets come in, packets go out, and
internally it's just another circuit.
