Configuring Directory Views for Avaya Modular Messaging systems

There are two ways to set up directory updates between multiple Avaya Modular Messaging (MM) systems:

• Each MM system provides updates directly to the other MM systems in the network (that is, without using Message Networking).
• Message Networking provides the updates to the MM systems in the network (that is, in a hub-and-spoke topology).

There are considerations for each directory update option.

Option 1: MM systems provide the directory updates directly to other MM systems

This is the most common option for setting up directory updates between MM systems. In this scenario, each Modular Messaging system provides directory updates directly to every other Modular Messaging system in the network. Updates occur more quickly using this option, but it requires more administration.

To configure the MM systems and the Message Networking system to use this option, you must perform the following administration on the MM systems and the Message Networking system:

• Administer each MM system as an LDAP Machine Type on the other MM systems in the network.
• Administer each MM system as a remote machine on the Message Networking system.
• On the Message Networking system, set the Subscriber Update Type on the Remote Machine Parameters page to Full for each MM system.
• Modify the Directory View for each MM remote machine on the Message Networking system to delete the other MM systems from the view. This will prevent both the MM system and the Message Networking system from providing the same directory updates.
• If there are two Message Networking systems in the network, each Message Networking system is defined as a remote machine on the other Message Networking system. In this case, you must modify the Directory View of the Message Networking remote machine on both Message Networking systems to remove the range of addresses that represent the MM subscribers.

Example

In the following example, there are two Modular Messaging systems, named MM1 and MM2, and there is a single Message Networking system in the network. To set up the Modular Messaging systems to provide updates directly to each other, the following administration is performed on each Modular Messaging system and on the Message Networking system:

• MM1:
  • Administer the MM2 system as an LDAP Machine Type on the MM1 system.
• MM2:
  • Administer the MM1 system as an LDAP Machine Type on the MM2 system.
• Message Networking:
  • Administer the MM1 and MM2 systems as Avaya Modular Messaging remote machines on the Message Networking system.
  • Verify that the Subscriber Update Type on the Remote Machine Parameters page is set to Full for each of the Avaya Modular Messaging remote machines.
  • Modify the Directory View of the MM1 remote machine to delete the MM2 remote machine.
  • Modify the Directory View of the MM2 remote machine to delete the MM1 remote machine.

Option 2: Message Networking provides the directory updates between the MM systems

In this scenario, the Message Networking system provides the directory updates between the Modular Messaging system. The advantage of this option is that if you have many MM systems in your network, the Message Networking system can simplify the update process and administration.

To configure the MM systems and the Message Networking system to use this option, you must perform the following administration on the MM systems and the Message Networking system:

• Administer each MM system as a remote machine on the Message Networking system. Do not administer each MM system on the other MM systems in the network. The MM systems would then only know about the Message Networking system and not about each other.
• On the Message Networking system, set the Subscriber Update Type on the Remote Machine Parameters page for each MM system to Full.

Note: The Subscriber Name field, when sent from an MM system to another MM system through a Message Networking system, will contain a numeric Node ID value as assigned by the Message Networking system.

Example

In the following example, there are three sites. Each has multiple Modular Messaging systems and each has a Message Networking system (hub and spoke topology):

To set up Message Networking to provide the directory updates, the following administration is performed for each site:

• New York:
  • On the MN A system, administer NY1 through NY3 and and MN B and MN C as remote machines.
  • Verify that the Subscriber Update Type on the Remote Machine Parameters page is set to Full for each of the Avaya Modular Messaging remote machines.
• Denver:
  • On the MN B system, administer DV1 through DV4 and MN A and MN C as remote machines.
  • Verify that the Subscriber Update Type on the Remote Machine Parameters page is set to Full for each of the Avaya Modular Messaging remote machines.
• Orlando:
  • On the MN C system, administer OL1 through OL5 and MN A and MN B as remote machines.
  • Verify that the Subscriber Update Type on the Remote Machine Parameters page is set to Full for each of the Avaya Modular Messaging remote machines.
