I don't think it is needed to be able to ping an interface to add it with
the loadhost command. I think it can be created as down and then unmanaged.
There is an option in loadhost to not try to ping an interface when it is
created.
Anyway, It would be difficult to add a loopback interface somewhere for
each of the 200+ routers that we are talking about.
is it not possible to import a value for the object in the database in
order for Netview to see it as a router ?

Interesting problem:
Have a router -- but no SNMP access. I only have one known interface, but
want to see it on submap as a router. You are using loadhosts -- so the
router interface gets loaded with the proper subnet mask -- good!
Suggestion:
Create additional interfaces in your network that can be "vitually"
identified with the routers so that NetView will see the devices as
routers.
Here is how:
For a router like this, create a new loopback interface on a single
computer which is NOT running SNMP. In your /etc/hosts add those
interfaces so that one interface gets assigned to each router by hostname.
All those interfaces should be in the same subnet that does not currently
exist in your network. The computer with loopbacks should be on the same
subnet as your NetView server (to make routing simpler). It could be a
small PC running Linux or Windows. At your NetView server you should add
a net route statement so that any pings going to that virtual loopback
network goes to that computer interface. Now you should be able to ping
those loopbacks from NetView server, if you can't check the default route
in that computer and also check the NetView host route statement. At this
point you should be able to ping every loopback interface you added.
Now do a loadhost of one of those loopback addresses. Because the
/etc/hosts has it as the same hostname of router, it should be added to it
and show up as a router in NetView. If this works, you can simply add
more loopback interfaces for the rest of the routers you want to manage
this way. If you want to, you can go into those devices and unmanage the
virtual loopback interface after NetView discovers it.
Let me know if are willing to try this...and if it works!

In the environment I am working with, it is not possible to do that. All
the devices that I want to see represented on the map as routers are
controlled by a provider that provide the WAN connectivity to every sites
for the customer. We don't have snmp access to any of theses devices and
therefore each remote site is represented as an "Isolated" network on the
map.
We already load theses devices with loadhost just to make sure that the LAN
interface get the proper subnet mask. We don't know the ip of any of the
WAN interfaces of the routers. We just have the IP of the LAN interface
that connect to our LAN. I would like for each site to see that device
represented as a router (ie stick out of the segment on the map) even if it
is present in Netview with only it's LAN interface. That would help the
operator see when the WAN connectivity goes down for the site.

along with Leslie's idea, you also want NetView to discover all the
interfaces on that router. with SNMP access, NetView would do that
automatically. Without SNMP access you will want to put all the
interfaces into your netmon seed file. Do that after you have updated
your /etc/hosts so that they all resolve to the same host name.
