To all DECnet gurus:
Is the following topology legal?
A:: B::
+----+ +----+
| |--dmr----------dmr--| |
+----+ +----+
| |
---------ether------------------------
The reason for this topology is that the ethernet is more than 1
physical segment, connected via level-2 bridges running over a long
phone circuit. The dmr circuit would be used as a backup in case the
ether-ether bridge failed. I know that redundant circuits are normally
supported by DECnet, but I am not sure about the above case. The reason
for the question is that after configuring the above topology, we started
seeing high levels of kernel/interrupt activity which was (apparently)
stopped by turning off the dmr circuit. An additional note: A:: and B::
are area routers in different areas.
