Your output appears to come from either an outdated in6.c 
or a custom version.  I expect to see something like the 
following for each interface address from netstat output:

Destination		Gateway		Flags		Netif
expire
-----------------------------------------------------------------------
2001:db8::1		link#1		UHS		lo0
2001:db8::2		link#2		UHS		lo0
-----------------------------------------------------------------------

Please verify your source file.
