[cisco-bba] PPPoE & L2TP

[Sebastian Dehne]

Hi list,

I'm trying to forward a ppp (pppoe) sessions wihout succes. I have tried
all kinds of example-configuration, but without success.

PPPoE-client --pppoe--> LNS --l2tp--> NAS

I see the l2tp-tunnel being created, but no ppp-session in it.

Outout fom the NAS:

v5#show debugging
General OS:
  AAA Authentication debugging is on
  AAA Authorization debugging is on

Radius protocol debugging is on
Radius packet protocol (authentication) debugging is on


VPN:
  L2X protocol events debugging is on
  L2X protocol errors debugging is on

Nov  4 13:46:27.484 CET:  Tnl 6986 L2TP: No more sessions in tunnel, shutdown (likely) in 10 seconds

Seen the fact that radius-debugging is switched; My conclusion is that
the proess doesnt reach AAA.

The NAS uses 12.2(15)T8 and the LNS 12.3(4)T.

can anyone help?

greetings,
Sebastian
