I'm looking for a little bit of help on an L2TP error.

I have a cisco 881 router which needs to make an L2TP connection, the conf:

l2tp-class PW
     hostname C881

pseudowire-class L2TP
  l2tpv2 encapsulation
  protocol l2tpv2 PW
  local ip interface FastEthernet4

FastEthernet4 interface
  ip address dhcp
  auto duplex
  auto speed

Virtual-PPP1 interface
  ip address negotiated
  no ip redirects
  no ip unreachables
  no ip proxy-arp
  ip mtu 1300
  ip verify unicast reverse-path
  ip tcp adjust-mss 1200
  load-interval 30
  no cdp enable
  ppp chap hostname mylogin @ realm
  ppp chap password 0 xxx
  ppp ipcp dns request
  ppp ipcp route default
  pseudowire 10.10.10.1 1 l2tpv2 pw-class L2TP encapsulation

ip route 0.0.0.0 0.0.0.0 Virtual-PPP1
ip route 10.10.10.1 255.255.255.255 FastEthernet4 dhcp




In debug L2TP all i have:
