Sounds like a bug, but I cannot reproduce it.

With this kernel
kern.version=OpenBSD 5.0 (GENERIC) #30: Wed Aug 3 16:08:44 MDT 2011

and this carp device

ndp and ping6 fdd7:e83e:66bc:7:200:5eff:fe00:101 works for me.
To figure out what is going on I need more information:
- Is this a regression? Did it work before?
- Please set sysctl net.inet6.icmp6.nd6_debug=1 and look for errors in dmesg.
- What icmp6 packets do you see with tcpdump?
- How is your configuration and setup?
