Configuring the MPLS VPN-Tagging Server

The MPLS VPN-Tagging Server, described in the VMware Smart Assurance MPLS Manager Discovery Guide Supplement, enables IP Availability Manager to correctly represent in its repository certain overlapping IP-address configurations.

By default, the MPLS VPN-Tagging Server is configured to connect to an IP Availability Manager named INCHARGE-AM. You can edit the vpn-tagging.conf file to change this name or to configure additional IP Availability Managers as sources for the MPLS VPN-Tagging Server. The object definition to be edited in the vpn-tagging.conf file is:

InChargeDomain::InChargeDomain_INCHARGE-AM {
       Type = "AM"
       DomainName = "INCHARGE-AM"
       DisplayName = "INCHARGE-AM"
}

The object definition serves as a template for specifying IP Availability Managers as sources for the MPLS VPN-Tagging Server.

To change the default IP Availability Manager name, or to add an additional IP Availability Manager as a source for the MPLS VPN-Tagging Server:

1. Go to the BASEDIR/smarts/bin directory in the MPLS Management Suite installation area and type the following command to open the vpn-tagging.conf file:

                  sm_edit conf/vpn-tagging/vpn-tagging.conf
               

   The object definition to be edited in the vpn-tagging.conf file is:

   InChargeDomain::InChargeDomain_INCHARGE-AM {
          Type = "AM"
          DomainName = "INCHARGE-AM"
          DisplayName = "INCHARGE-AM"
   }
   

2. Find the section, Instances of AM Server, and go to the section below the comments and find the following object definition:

   InChargeDomain::InChargeDomain_INCHARGE-AM {
          Type = "AM"
          DomainName = "INCHARGE-AM"
          DisplayName = "INCHARGE-AM"
   }
   

3. Make the following edits to the object definition:

4. On the InChargeDomain and DomainName lines, change INCHARGE-AM to the name of your IP Availability Manager.

5. On the DisplayName line, change INCHARGE-AM to the name that you want to see for the IP Availability Manager in the Global Console.

   Example of a customized object definition for an IP Availability Manager:

   InChargeDomain::InChargeDomain_ASIA-AM1 {
          Type = "AM"
          DomainName = "ASIA-AM1"
          DisplayName = "ASIA-AM1"
   }
   

6. To specify additional IP Availability Manager sources, copy and paste additional versions of the InChargeDomain object definition, and then follow the directions given in step 3.

7. Save and close the file.

   The modified version of the vpn-tagging.conf file is saved to the BASEDIR/smarts/local/conf/vpn-tagging directory.

8. If the MPLS VPN-Tagging Server was running before you edited the vpn-tagging.conf file, restart the MPLS VPN-Tagging Server.

   At startup, the MPLS VPN-Tagging Server reads the vpn-tagging.conf file, loads the file’s configuration information to the repository, and attempts to connect to the one or more IP Availability Managers that are specified in the file.

   The procedure for configuring IP Availability Manager for overlapping IP discovery is given in “Enabling overlapping IP address discovery” on page 77.
