Thanks Phil, the event-options is something a coworker of mine is 
suggesting also.  I'll keep that option in my back pocket for research 
should other options fail to lead us to a satisfactory result.  The JTAC 
is telling me Active Lease Query needs to be enable along with Bulk 
Lease Query.  I tried it, but don't see anything further with Active 
Lease Query, so I'm waiting on JTAC to respond.  Previously, with a few 
Bulk Lease Query commands enabled, I do see the Juniper router do a TCP6 
connection to the DHCPv6 server port 547... this occurs when I do the 
manual request.  My coworker has configured KEA to allow BLQ, and he 
does see the activity and we see it working...again, only when I the 
manual request command shown below.  I don't see this occur following a 
reboot of the Juniper router, which is the desired outcome, since IA_PD 
routes become unreachable when the binding table is cleared, and I need 
it to be populated immediately following a router reboot to minimize 
downtime.
