[c-nsp] ASR9K as PPPoE L2TP LAC

[Carlo]

Hello all,

I'm trying to configure ASR9K to act as L2TP LAC for PPPoE sessions and I'm
having some problems.
The LNS is a IOS-XE router.
The L2TP tunnel parameters are passed via Radius as follow:

Service-Type = Outbound-User
Cisco-AVPair += "vpdn:l2tp-tunnel-password=ciscotest"
Cisco-AVPair += "vpdn:ip-addresses=10.10.10.2"
Tunnel-Medium-Type:0 += IPv4
Tunnel-Type:0 += L2TP

The tunnel goes up but just a few moment it's disconnected.
I've tried to enable some debugs and I see this errors that I can't
uderstand
