PPPoE
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
Emulating PPP over Ethernet (PPPoE) sessions was initial
|
|
|
|
|
use case of the BNG Blaster supporting 1:1 and N:1 VLAN
|
|
|
|
|
mode.
|
|
|
|
|
|
2022-10-27 16:31:25 +00:00
|
|
|
The BNG Blaster concept is leaned to the idea of fail-fast.
|
2022-06-08 11:18:55 +00:00
|
|
|
Therefore PPPoE sessions may not be established if not all
|
|
|
|
|
expected conditions are fulfilled. PPPoE sessions become
|
|
|
|
|
established only if all enabled network protocols
|
2022-10-27 16:31:25 +00:00
|
|
|
(IPCP and IP6CP) are negotiated successfully.
|
2022-06-08 11:18:55 +00:00
|
|
|
If IPCP is configured to request two DNS servers,
|
|
|
|
|
it fails if only one is returned.
|
|
|
|
|
|
2022-10-27 16:31:25 +00:00
|
|
|
The BNG Blaster is not optimized for robustness. The opposite is
|
|
|
|
|
the case, to ensure it failed if the device under test behaves faulty.

LCP Vendor Extension
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
This chapter refers to RFC 2153 PPP vendor extensions.
|
|
|
|
|
|
2022-10-27 16:31:25 +00:00
|
|
|
Per default, all LCP vendor-specific requests will be rejected sending a
|
|
|
|
|
LCP code-reject message. With the LCP option ``ignore-vendor-specific``
|
|
|
|
|
enabled in the configuration, those messages will be ignored as required
|
|
|
|
|
to emulate different CPE behaviors.
|
2022-03-30 23:47:00 +02:00
|
|
|
|
2022-11-17 22:33:13 +00:00
|
|
|
The LCP option ``connection-status-message`` allows accepting LCP vendor requests
|
2022-03-30 23:47:00 +02:00
|
|
|
with any OUI if kind is set to ``1`` by responding with vendor request of
|
2022-10-27 16:31:25 +00:00
|
|
|
kind ``2``. The OUI from the request is copied to the response in this case.
|
|
|
|
|
The value from the request is stored in the session as ``connection-status-message``.
