[rbak-nsp] L2TP & IPv6 Subscriber

[Florian Lohoff]

Hi,

we are having trouble assigning IPv6 Addresses to L2TP Subscribers.
It seems ND is not working although the same setup works for PPPoE
attached subscribers.

We see an error in the logs:

Aug 29 01:32:27.807: %PPAINFRA-3-IFACE_ERROR:
	56aeeb9c/0018207457/563100000:01/EPPA/EU00:Circuit
	255/16:511:63/5/2/4221 IPv6 MTU 0 invalid; Retaining valid MTU 1442 -
	0006a09c 000ae05c 00069c08 0007b3b8 000788c2 00074f86 000bb2c8 0007489c
	000acfa0 000acf78 00000000'

In the correct case we see the nd profile beeing assigned to the 
subscribers circuit - this is missing when terminating the L2TP
Subscriber onto the same subscriber default.

This is SEOS-6.5.1.

 subscriber default
   ip address pool name POOL_DEFAULT
   ip source-validation
   ppp mtu 1492
   dns primary p.r.e.8
   dns secondary p.r.e.8
   ipv6 framed-pool POOLv6ND_DEFAULT
   ipv6 nd-profile nd-profile-default
   ipv6 delegated-prefix maximum 2
   dns6 primary  pref:fix::53
   dns6 secondary pref:fix::53
   ipv6 source-validation

[ ... ]

 nd profile nd-profile-default
!
 router nd
  preferred-lifetime 900
  valid-lifetime 1800
