3.1. Format of the Access Network Identifier Sub-Option
|
|
|
|
The Access Network Identifier sub-options are used for carrying
|
|
information elements related to the access network to which the
|
|
mobile node is attached. These sub-options can be included in the
|
|
Access Network Identifier option defined in Section 3. The format of
|
|
this sub-option is as follows:
|
|
|
|
0 1 2 3
|
|
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

|
|
|
|
ANI Type: 8-bit unsigned integer indicating the type of the Access
|
|
Network Identifier sub-option. This specification defines the
|
|
following types:
|
|
|
|
0 - Reserved
|
|
|
|
1 - Network-Identifier sub-option
