Bernard is right. Regardless of the type of device, if you
discover one interface it will discover all of them. At V6, Netview
is pretty good at allowing the duplicate and moving it to the node
on which that interface is UP. It would prefer that the other one is
Administratively Down.
When you discover these nodes, use a seedfile and make sure
to specify the unique addresses.

Subject: RE: [NV-L] Duplicate ip addresses in network.
I agree with Emmanuel, and ask one question : are those addresses assigned
to routers interfaces ?
In that case, I am not sure of whether you can ask netmon to discover only
part of a device : during a poll for config, netmon 'sees' all interfaces
of
a router, what happens if an interface is assigned an address defined as
negative entry in the seed file ?
