By default, IP Availability Manager is not enabled to perform overlapping IP address discovery. To enable this feature, set the following parameters in IP Availability Manager’s tpmgr-param.conf file to the shown values:
DisableOverlappingIP FALSE UseVPNIP FALSE EnableShadowIP TRUE (default)
Be aware that in IP Manager 7.0.4, the UseVPNIP value is TRUE by default because of the following uncommented entry in the tpmgr-param.conf file:
Because this entry has been deleted from the tpmgr-param.conf file in IP Manager 8.1, add UseVPNIP FALSE to the tpmgr-param.conf file to ensure that tagged IP and IPNetwork objects, not VPNIP and VPNIPNetwork objects, are created for the discovered VRF IP addresses.
To enable overlapping IP discovery:
Go to the BASEDIR/smarts/bin directory in the IP Manager installation area and type the following command to open the tpmgr-param.conf file:
Set the following three parameters to the values shown:
DisableOverlappingIP FALSE UseVPNIP FALSE EnableShadowIP TRUE
Save and close the file.
The modified version of the tpmgr-param.conf file is saved to the BASEDIR/smarts/local/conf/discovery directory.
If IP Availability Manager was running before you edited the tpmgr-param.conf file, type the following command from BASEDIR/smarts/bin to make your change take effect:
sm_tpmgr -s <IP Availability Manager instance name> --load-conf=tpmgr-param.conf
