Identity and IP Address Prefix

The first parameters you configure for a realm are its name (a unique identifier) and an IP address prefix and subnet mask.

The IP address and subnet mask establish a set of matching criteria for the realm, and distinguishes between realms that you assign to the same network interface.

To configure a realm’s identity and IP address prefix in the ACLI:

1. identifier—Enter the name of the realm. This parameter uniquely identifies the realm. You will use this parameter in other configurations when asked for a realm identifier value.
2. addr-prefix—Enter the IPv4 or IPv6 address and subnet mask combination to set the criteria the Oracle® Enterprise Session Border Controller uses to match packets sent or received on the network interface associated with this realm. This matching determines the realm, and subsequently what resources are used for that traffic. This setting determines whether the realm is an IPv4 or IPv6 realm.

   This parameter must be entered in the correct format where the IPv4 or IPv6 address comes first and is separated by a slash (/) from the subnet mask value. For example, 172.16.0.0/24.

   The default for this parameter is 0.0.0.0. When you leave this parameter set to the default, all addresses match.
