Enabling overlapping IP address discovery

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:

UseVPNIP TRUE

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:

1. 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:

                  sm_edit conf/discovery/tpmgr-param.conf
               

2. Set the following three parameters to the values shown:

                  DisableOverlappingIP FALSE
                  UseVPNIP FALSE
                  EnableShadowIP TRUE
               

3. Save and close the file.

   The modified version of the tpmgr-param.conf file is saved to the BASEDIR/smarts/local/conf/discovery directory.

4. 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
