When Running HSRP, "Duplicate IP Address" Messages Appear in HP OpenView NNM
Event Browser
----------------------------------------------------------------------------
---
This technical tip addresses the problem of "Duplicate IP Address" messages
appearing in (and sometimes flooding) the Hewlett-Packard (HP) OpenView
Network Node Manager (NNM) event browser when running Hot Standby Router
Protocol (HSRP).
Note: This document originated from HP technical support. If you would like
more information or have further questions on this issue, you may wish to
contact HP:
http://www.openview.hp.com
As an example, you could see this problem when you have two RSMs with HSRP
enabled. One message would display in the event browser for each IP address
configured on the RSMs.
Note: This workaround causes HP OpenView to poll the Hot Standby routers
with an incorrect community string. If configured, these routers could
potentially flood your management station with Authorization Failure traps.
An unsupported method of working around this problem is to create a file
called netmon.noDiscover in the /etc/opt/OV/share/conf directory that
contains all the Hot Standby IP addresses. This causes HP OpenView's
discovery mechanism to disregard these addresses before beginning to poll
them.
The following steps detail a Hewlett-Packard recommended procedure that
allows HP OpenView NNM to operate correctly in an environment that includes
Cisco routers supporting HSRP.
Obtain a list of all Hot Standby addresses in the management domain. These
are the IP addresses that will migrate from one physical router to another
when one router goes down.
Use the "Options->SNMP Configuration" menu item to add an entry for each Hot
Standby address. In each entry, enter the IP address in the Target field,
and an incorrect community name in the Community field. This causes all SNMP
access to the Hot Standby address to fail because of the incorrect community
name.
Make sure that none of the Hot Standby addresses resolve to the same
hostname as any of the real routers in the /etc/hosts file or the
nameserver.
If the "I" flag had previously been added to the
/etc/opt/OV/share/conf/oid_to_type file in an attempt to fix the HSRP
problem, it can be safely removed at this time.
Stop network monitoring with the ovstop netmon command.
Find all instances of the Hot Standby addresses in your map, and delete any
interface containing these addresses. This may need to be repeated for all
maps, if you have multiple OVW maps.
If any of the routers in the map look incorrect (that is, they have
incorrect addresses or interfaces associated with them), then delete these
routers as well. They should be rediscovered later.
Clear the IP address-to-name mapping cache with the xnmsnmpconf -clearCache
command.
Restart network monitoring with the ovstart netmon command.

I've heard of this one before.
HSRP drives OpenView nuts.
As others have already pointed out, you can disable this event in Event
Configuration. I don't know about you, but I have way too many other
problems to shoot to be worrying about duplicate IP issues, so losing this
event shouldn't hinder your ability to manage your network.
I would check on OVFORUM (http://www.ovforum.org) to see if any of the OV
gurus there have an answer. I seem to remember a couple of questions about
HSRP on that group lately.

Need some info from all you HPOV experts, I'm seeing alarms from a router
every 62 minutes. The alarm states "router reports address 0x00000c07ac00
for 10.10.10.1, router reported 0x00d0bbcc9400 via snmp"
-the first mac address is the virtual mac address for the standby interface,
-the second mac address is one of the ethernet interfaces from the router.
>From reading the detail information on the trap it appears this info is
generated because the node has more than one mac for the interface.
Can anyone help me stop these traps, I'm about to set up a lot more standby
interfaces so it'll become a real nuisance then.
Thanks
