I'd have to check the docs, but IIRC the node list doesn't get transmitted

area reachability and answer yes or not to the reachability of any node
under their scope (i.e. in their area), but do not transfer the whole area
contents to other nodes.
To see new nodes in SHOW KNOWN NODES you'll have to do a COPY KNOWN NODES
from a node that already knows the nodes you are interested in, then you'll
see all the nodes on a reachable area marked as reachable (even if the
specific node is powered off).
But do not take for granted this whole theory. :-)

The DECnet routing works just as Gerry told.
Area routers exchange area information among themselves by sending router hello's. Endnodes inform the area routers about their existence by sending endnode hello's and L1 and L2 routers send router hello's which also the endnodes listen to.
All the routing information is sent by multicasting.
So all nodes learn the needed information from the network without any operator efforts.
That is true if the network is configured by the rules. :)

At the moment I cannot remember if @SYS$MANAGER:NETCONFIG.COM asks something
about configuring a node as an area router, but I'm assuming that it doesn't
ask anything, or you wouldn't be here asking for help. :-)
As a starting point you may just type the following:
$ RUN SYS$SYSTEM:NCP
NCP> SET EXECUTOR STATE SHUT
NCP> DEFINE EXECUTOR TYPE AREA
NCP> EXIT
$ @SYS$MANAGER:STARTNET
If I'm not wrong, this should be enough to transform your node into an area
router; then you may want to revise your configuration to tune it better.
HTH, :-)

Yes, quite so.
The NETCONFIG.COM asks only if you want to configure a router or end node. When it asks that you should answer that you want to run the node as a router, but before you start DECnet, you should do the DEFINE statement as in Gerry's message.
It takes some time before the router hello's and endnode hello's traverse the network, but after a while you should see the other areas from your Area router node and others should see your area.

Kari
I periodically COPY KNOWN NODES FROM MIM on all my machines, I consider MIM to be the canonical host list. Not sure if this is correct but has worked for me so far.

The nodes that I have powered up at the moment are:
42.1 CANADA (the area router)
42.2 DAFFY
I was able to do a COPY KNOWN NODES FROM 1.400 which populated my node list. Is this something I need to do manually, or is this an automatic process that I don't have set up properly?

You are correct - NETCONFIG doesn't ask about level 1 or 2 - just whether you're a router or not. Your commands (which I'm sure I tried some time during the last 24 hours, but I'm not sure) followed by a reboot seems to have fixed it. Thanks!

Makes sense, it shows 42.1 as next node (but no name, which is legal though normally you d load names for each defined address).
