Yes, it's possible. It's absolute necessary with the
HSRP support. This is from /usr/OV/conf/netmon.seed.
# Hot Standby Routing Protocol (HSRP)
Support
#
# HSRP interfaces may be specified here
for netmon to acknowledge them.
# Only the public IP address need be
entered.
#
# Use the prefix '%', and use the same
syntax for ranges and wildcards
# described above for positive seed
entries. For instance, if 1.1.1.1
# is the IP address of the HSRP interface
that switches between two
# routers, enter,
#
# %1.1.1.1
Other reasons may exist for doing so and NV can handle
accidental duplicate interface adddresses on routers but it doesn't like
it. It definitely won't handle routers whose primary interface addresses
are duplicated; as you've seen it will delete one of them. To give you a
better answer we need to know why there are duplicate addresses. The
solution may be to use CNAT or it may be to identify the devices as HSRP
or it may be simply to clean up your network interface definitions.
If you search the archives for this mailing list you will see
a few cases where the HSRP support is used to handle duplicate IF addresses
present for other reasons.
You simply haven't given enough information for anyone to send
an intelligent answer. Why do your routers have duplicate
addresses?

[nv-l] Managing routers with duplicated IP address
Dear friends,
Our Environment:
AIX 4.3.3 ML-10
Tivoli Netview
7.1.4
Tivoli Framework 3.7.1
ITEC 3.9
We´d like to know if it´s possible to manage a router with an
IP address duplicated on another router ?
Thanks in advance
