To add IP addresses to an IPMP group, use the ipadm create-addr command. For IPMP configuration, an IP address can be either a data address or a test address. A data address is added to an IPMP interface, while a test address is added to an underlying interface of the IPMP interface. The following procedure describes how to add IP addresses that are either test addresses or data addresses.
# ipadm create-addr -a address ipmp-interface
An address object is automatically assigned to the IP address that you just created. An address object is a unique identifier of the IP address. The address object's name uses the naming convention interface/random-string. Thus, address objects of data addresses would include the IPMP interface in their names.
# ipadm create-addr -a address under-interface
An address object is automatically assigned to the IP address that you just created. An address object is a unique identifier of the IP address. The address object's name uses the naming convention interface/random-string. Thus, address objects of test addresses would include the underlying interface in their names.
