To enhance overlapping IP address discovery, you, as an administrator, enable IP Availability Manager to interoperate with the VPN-Tagging Server.

Assuming that the DisableOverlappingIP, UseVPNIP, and EnableShadowIP parameters in the tpmgr-param.conf file are set as specified in the previous section, you do so by setting the following parameter in IP Availability Manager’s discovery.conf file to TRUE:

importExternalTagsConnections TRUE

In addition, you need to enable the VPN-Tagging Server to interoperate with IP Availability Manager. You do so by adding IP Availability Manager as a source to the VPN-Tagging Server.

To enable interoperability between IP Availability Manager and the VPN-Tagging Server:

  1. Consult the IP Manager documentation and follow the instructions to set the following parameter in the discovery.conf file to the value shown:

                   importExternalTagsConnections TRUE

  2. Consult the IP Manager Concepts Guide and follow the instructions to add IP Availability Manager as a source to the VPN-Tagging Server.

    The VPN-Tagging Server performs overlapping-IP and corresponding network-connection discovery in two vendor-specific environments: Cisco and Alcatel-Lucent. To complete the configuration of the VPN-Tagging Server, open the BASEDIR/smarts/conf/vpn-tagging/vpn-tagging.conf file (in the Network Protocol Manager installation area) and perform the following additional tasks:

    • Mandatory and for Alcatel-Lucent only: Add the Enable5620SAMDiscovery parameter with a value of TRUE to the vpn-tagging.conf file.

    • Optional and for Alcatel-Lucent only: Modify the default values of the AlcatelDiscoveryInterval parameter.

    • Optional and for Cisco only: Modify the default values of the DiscoveryFilter parameter.
