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.
To add data addresses to the group, type:
$ 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.
To add test addresses to the group, type:
$ 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.
