PPPoE Intermediate Agent
This chapter describes how the SAM1316-22 gives a PPPoE termination server
additional information that the server can use to identify and authenticate a PPPoE
client.
36.1 PPPoE Intermediate Agent Tag Format
If the PPPoE Intermediate Agent is enabled, the SAM1316-22 adds a vendor-
specific tag to PADI (PPPoE Active Discovery Initialization) and PADR (PPPoE Active
Discovery Request) packets from PPPoE clients. This tag is defined in RFC 2516
and has the following format for this feature.
The Tag_Type is 0x0105 for vendor-specific tags, as defined in RFC 2516. The
Tag_Len indicates the length of Value, i1 and i2. The Value is the 32-bit number
0x00000DE9, which stands for the “ADSL Forum” IANA entry. i1 and i2 are PPPoE
intermediate agent sub-options, which contain additional information about the
PPPoE client. The SAM1316-22 supports two formats for the PPPoE intermediate
agent sub-options: private and TR-101.
36.1.0.1 Private Format
There are two types of sub-option: “Agent Circuit ID Sub-option” and “Agent
Remote ID Sub-option”. They have the following formats.
