- The address TLV looks as follows:

- | Number of addresses |
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | IDRP encoded address |
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-
- An address is encoded in IDRP format:
-
- 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

- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | Address length | Address (variable) ...
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-
- PT: Protocol type
- 1 = NLPID format
- 2 = 802.2 format
-
- PT Length:
- Length of protocol field, 1 for PT = 1, and either 3 or 8 for
- 802.2 format depending if SNAP is used for PT = 2.
-
- The encodings for the other protocols have the following format:
-
- field: <SSAP><DSAP><CTRL><-------OUI------><protocl_TYPE>
- | | | | | | | | |
- bytes: 0 1 2 3 4 5 6 7 8
-
- where the first 3 bytes are 0xAAAA03 for SNAP encoded addresses.
- The OUI is 000000 for ethernet and <protocl_TYPE>
- is the assigned Ethernet type code for the particular protocol.
- e.g. for DECnet the encoding is AAAA03 000000 6003.
- for IPv6 the encoding is AAAA03 000000 86DD
