[c-nsp] DHCPv6 accounting on ASR1000

[Christian Schmit]

Hi Chris,
  
 I have tested 3.13 in the lab yesterday and can confirm that dhcpv6 
accounting is now working!
 As version 3.13 is quite new I hesitate to put in on our production ASR 
boxes.

I was also told there was no hope of having this work before 3.13. I
had a TAC case open from November 2012 to September 2013 for them to
finally tell me it was a feature request (enhancement...) that would be
integrated into 3.13. I am not yet running something so new.
