With Clearview IPMP, IPV6_BOUND_PIF isn't needed because you can get either behavior from IPV6_BOUND_IF. Specifically, you can specify an IPMP interface index when you want to send/receive over any IP interface in the group, and an underlying interface index when you want to send over a specific IP interface in the group (which is what e.g. in.mpathd uses to send/receive its probes). However, note that when used on underlying IP interfaces, this functionality is intended only for unicast traffic. -- meem
