Re: [nv-l] VRRP and Netview

[Michael Webb <mlwebb@us.ibm.com>]

Although your scenario involves VRRP, it could be that one or some of the HSRP interim fixes may help out in your situation.

All of the following HSRP Interim fixes listed below are now included in 7.1.3 FixPack2.  The first one listed below, IY38924, sounds like it may address one of your problems. You mentioned that from time to time the VRRP addresses appear on other devices.

In this case, for IY38924, NetView did not reassign the Virtual IP address to the HSRP router if it was first assigned to a workstation (or some other device) AND that workstation (or other device) had a different community string than the HSRP router.  Not sure if this applies to your current configuration.

Nevertheless, here are some HSRP interim fixes you may be interested in:

IY38924 Windows/UNIX An HSRP interface may be assigned to the IP forwarding workstation if it is discovered earlier than the router that actually owns the interface.

IY42541 Windows/UNIX Multiple interface down events generated for HSRP virtual interface.

IY43169 Windows/UNIX HSRP interface is discovered as a lone device after fix for IY38709.

IY48203 Windows/UNIX Don't add secondary interface to HSRP interface if its the same MAC address.

Hi Paul,

The Device are not routers but Nokia firewall.

In fact my seedile look like this

% VRRP for zone A
% VRRP for ZONE B
% VRRP for ZONE C
@IP for FW1 zone A (my management address)
@IP for FW2 zone B (my management address)

The kind of problem is for example:

The VRRP address for zone C is not discovered on my FW1 neither on my FW2 .
The command ovtopodump | grep @VRRP (for all the zone) return no lines.
But from time to time the VRRP addresses appear on other devices. But as
soon as netview discovered that the address does not belong to this device
netmon delete the interface and my node goes down.






Cordialement.

This sounds like a duplicate IP address problem, are you discovering
the device via the VRRP interface, if so, I would suggest using the
loopback address of the router for discovery.
