Enabling overlapping IP address discovery

Note:

This procedure is not applicable for IP Availability Manager versions 8.1.x and higher. The VPNIP attribute has been deprecated in release 8.1.x and 9.x. Refer to the Route Distinguisher (RD) IP tagging policy configuration procedures in the IP Manager Concepts Guide.

By default, IP Availability Manager releases prior to version 8.1.x are 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)

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
