Mobile Node Identified by its NAI

The Address section for a mobile node identified by its NAI contains the Type, SPI, and Pool labels. The NAI parameter enables you to identify mobile nodes through their NAI. The Address section, using the NAI parameter, has the following syntax:

[Address NAI]
     Type = Node
     SPI = SPI-identifier
     Pool = Pool-identifier

In order to make use of pools, you identify mobile nodes through their NAI. The Address section permits you to configure an NAI, as opposed to a home address. An NAI uses the format user@domain format. You use the Pool label to specify which address pool to use in order to allocate the home address to the mobile node.

The following table describes the labels and values that you can use in the Address section for a mobile node identified by its NAI.

Table 2-6 Address Section Labels and Values--Mobile Node Identified by its NAI


Label	Value	Description
`Type`	`node`	Specifies entry for a mobile node.
`SPI`	`n`	Specifies SPI value for the associated entry.
`Pool`	`n`	Allocates the pool from which an address is assigned to a mobile node.

You must have corresponding SPI and Pool sections for the SPI and Pool labels defined in an Address section with a mobile node identified by its NAI, as shown in the following illustration.
