<BR>
Have you tried:<BR>
Debug aaa authen<BR>
Debug aaa author<BR>
Debug aaa rad-attr<BR>
<BR>
Watch the output closely, you might see some attributes failing to find a place to hook them on.<BR>
Be aware that the SE400 doesn’t support compression algorithms.<BR>
Another caveat is that the first negotiation is done between client and AS5300, and secondly is done between client and SE400.<BR>
If these have different parameters for PPP, like MRRU, the client might expect a man-in-the-middle attack and close connection directly.<BR>
Keep all negotiated info between AS5300 and SE400 the same, else debug PPP negotiation to see where it fails on ...<BR>
<BR>
Kind regards,<BR>
<BR>
<BR>
Frans.<BR>

<BR>
</SPAN></FONT><FONT SIZE="2"><FONT FACE="Arial"><SPAN STYLE='font-size:10pt'>Hi All,<BR>
<BR>
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.<BR>
<BR>
Dialup modem ---> AS5300(LAC) ---> SE400 (LNS)<BR>
<BR>
Does anyone know if this is possible or have any experience (successful or unsuccessful) of doing this?<BR>
<BR>
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.<BR>
<BR>
I can provide debug/log message if anyone can help.<BR>
<BR>
Thanks,<BR>
<BR>
Carl<BR>
