Note that you can also fool Netview into doing this for you by putting the
two addresses in the /etc/hosts file (assuming you are using hosts as the
primary name resolver) with the same exact name. Delete the low-level
objects it already found and rediscover them. Whether you call this
clever or stupid, it is at least predictable. It will get them on the map,
but
you can do little else with them without SNMP.

You should have SNMP access, and read is sufficient, for any device you
are expected to manage. SNMP means simple network management
protocol. If you are being asked to managed these devices, you are
on solid ground to request snmp access. If 'they' don't want to give it to
you, then you have a business process problem. If it is insurmountable
(eg the router belongs to another group or company, and is on the edge
of your realm), then you have to resort to the 'fake router' solution that
Steve describes. You will only know up/down status.

If you manually add interfaces to one of the existing router interface
objects,
Netview is clever enough to delete the other interfaces with same address,
and add
the router to the IP map level.

That's not very clear:
i.e. with no snmp, Netview will have found these objects:
COmputer1, Ip address 1.1.1.1
Computer 2, IP address 2.2.2.2


These are in fact the IP addresses of your router.
If you double click on COMputer1 symbol, then edit add object, and add an
interface
with ip address 2.2.2.2
Netview will convert Computer1 symbol to a router symbol, add it to the IP
level
map, and remove computer2 symbol.

But clearly, getting SNMP access to these things is much better.
