It depends. Just polling routers which have some duplicated interfaces,
NetView can cope with.
If you wish to see the routers beyond such interfaces, then you would need
a CNAT solution.
NetView should be ok provided for every loopback address you also put the
address a 2nd time in netmon.seed with a dollar sign to force snmp polling.
e.g.
1.2.3.4 #Router
$1.2.3.4 #Force snmp
If you wish traps to be picked up correctly (as well as polls), then on the
routers you may wish to force the source ip address of the traps to the
same as the polled loopback
address. On a Cisco this would be
snmp-server trap-source interfacename
