[nsp] L2TP from 7200 to ERX

Hi all,

I am able to configure l2tp between 2 Cisco boxes (LAC and LNS). But l2tp
failed when Cisco is the LAC and a ERX is a LNS.

I have a working l2tp lns configuration on the erx that is working well, and I
am using the same configuration to interact with the Cisco 7206, but doesn't
seems to work.

Do you guys have any past experience doing l2tp from a cisco box to a ERX?

My setup is as follows:

<--------- PPP ----------><-----L2TP---->
CPE --- Cisco 7206 --- Cisco 7200 ---- ERX

Configuration on the 7206 as a LAC
boot system flash slot0:c7200-g4js-mz.122-15.T.bin

vpdn-group 1
 description Cisco LAC to ERX LNS
  protocol l2tp
 initiate-to ip  priority 1
 local name cisco-lac
 l2tp tunnel password 7 0010161510

interface ATM1/0.200 point-to-point

 ip unnumbered FastEthernet0/0.1

 ppp authentication pap

Any advise would be appreciated. Thanks.
