Okay I see what you mean. I guess my approach was to do an open discovery
(possible in my network but not in others perhaps) and then use ovobjprint
to dump the subnets into a file. I just figure NETMON is going to be as good
at "polling" things as any script I would write. thanks for the info.

What I'm after is a list of networks. Object info gives you interface
addresses and masks.
Yes, you want to discover your network first, and take a stab at arranging
it. Once
you decide where you want to put things, then you will want to generate a
location.conf
file that will not leave a lot of stuff laying out for you to put away.
Especially in V7, since
it will put routers away if you tell it what to do with all networks for
the router.
So you want to generate at the very least a list of all configured
networks for each
router in the map. Then programmatically arrange those network entries in
the
desired groupings in the location.conf file. Then rediscover and see how
well it
puts things away. Repeat as necessary.
I assume this is what Don is trying to do as well. Not do the discovery,
but build
a location.conf to handle what does get discovered.

Okay I am still missing the point. What is it that this produces that is of
use? Wouldn't using netmon.seed with the router names in it (with discovery
turned off) still produce the same data that could be ripped out of
ovobjprint or ovtopodump? What am i missing?

What I do is a pretty simple but I don't have a sample script.
Given a list of nodes, use a simple script or commandline awk to
produce a file with a record like this for each node:
rnetstat -I <nodename> | grep -v Network | awk '{print "<nodename> " $4}'
Then run that file and capture the output. That $4 returns all of the
networks to
which the node belongs. That parm on rnetstat is a capital i. A very useful
command. If you have a list mapping routers to sites and maybe parent
site,
you can modify the record above to produce the exact update record for the
location.conf.
(I do it this way because I don't know how to run an awk with a variable in
it.)
Warning: this approach, with no wildcards, can lead you over the 1000
record
max. In that case, in V6, be sure to get the patch from Support and follow
the
instructions for enabling large location.conf files.

Um, what am I missing? Isn't this what NETMON does? I populates a database
with information about the interfaces?

I am trying to automate much of my map layout using the location.conf file.
Unfortunately all I have been given is a list of loopback addresses for
about 700 routers and another list of hubs/switches. Has anyone out there
written a script that will read a file (say netmon.seed) and poll each IP
listed and return a list of configured/enabled/up interfaces along with
their IP, network number, and mask? I would imagine this would be a useful
tool so hopefully someone has already done this. Any pointers would be
appreciated.
