 I am experiencing the identical behavior on the following releases:
 
 6.3-RELEASE-p4
 6.4-PRERELEASE (as of Sep 6)
 
 I have reproduced the problem on both amd64 and i386, on both physical  
 interfaces and VLAN interfaces.
 
 The problem is the same:
 - two machines,  both configured correctly
 - both machines can ping6 each other
 - carp configures correctly, and announcements are observed on the  
 relevant LAN via tcpdump
 - one machine goes to MASTER and one goes to BACKUP
 - an additional machine on the same LAN can ping6 both machines
 - none of the three machines can ping (or route through) the CARP IPv6  
 address
 
 However, I'm *assuming* these are the CARP announcements (since they  
 are from the right IPv6 addresses and MASTER/BACKUP status seems to  
 work:

 11:54:52.855924 IP6 A:B:C:D::1 > ff02::12: ip-proto-112 36
 11:54:53.893300 IP6 A:B:C:D::1 > ff02::12: ip-proto-112 36
 11:54:54.930386 IP6 A:B:C:D::1 > ff02::12: ip-proto-112 36
 11:54:55.967965 IP6 A:B:C:D::1 > ff02::12: ip-proto-112 36
 11:54:57.004987 IP6 A:B:C:D::1 > ff02::12: ip-proto-112 36
 11:54:58.042481 IP6 A:B:C:D::1 > ff02::12: ip-proto-112 36
 
 I would be happy to help troubleshoot this problem in any way possible.
 
 Thanks,
 Jeff
