test case program
My test program attached.
NOTE: You need to modify it with your /64 address in the location with a
comment.
Here's some of my truss output with concurrent runs on 13.4 and 14.1
the 14.1 machine... (command "hive foo" i.e. one argument to cause ipv6
case...)
NOTE this receives the multicast messages...
