[rbak-nsp] Cisco AS5300 L2TP forwarding to Redback SmartEdge

[Frans Legdeur]

Hi Carl,

Have you tried:
Debug aaa authen
Debug aaa author
Debug aaa rad-attr

Watch the output closely, you might see some attributes failing to find a
place to hook them on.
Be aware that the SE400 doesn¹t support compression algorithms.
Another caveat is that the first negotiation is done between client and
AS5300, and secondly is done between client and SE400.
If these have different parameters for PPP, like MRRU, the client might
expect a man-in-the-middle attack and close connection directly.
Keep all negotiated info between AS5300 and SE400 the same, else debug PPP
negotiation to see where it fails on ...

Kind regards,


Frans.

Subject: [rbak-nsp] Cisco AS5300 L2TP forwarding to Redback SmartEdge

Hi All,
 
I'm trying to dial in to a Cisco AS5300 and have it L2TP forward the PPP
session to a context on a Redback Smart Edge for termination.
 
Dialup modem ---> AS5300(LAC) ---> SE400 (LNS)
 
Does anyone know if this is possible or have any experience (successful or
unsuccessful) of doing this?
 
I've got as far as the AS5300 seemingly bringing up the L2TP tunnel
successfully but the SE fails to terminate dialup users PPP session in the
context specified by RADIUS.
 
I can provide debug/log message if anyone can help.
 
Thanks,
 
Carl
