3430 3.1. Format of the Access Network Identifier Sub-Option
3431
3432 The Access Network Identifier sub-options are used for carrying
3433 information elements related to the access network to which the
3434 mobile node is attached. These sub-options can be included in the
3435 Access Network Identifier option defined in Section 3. The format of
3436 this sub-option is as follows:
3437
3438 0 1 2 3
3439 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

3444 ANI Type: 8-bit unsigned integer indicating the type of the Access
3445 Network Identifier sub-option. This specification defines the
3446 following types:
3447
3448 0 - Reserved
