Using the tunnel endpoint as both the start_addr & end_addr works.  When 
I first tried, I had "kind" set to 0 in both rows of 
child_config_traffic_selector table.  I have no idea what "kind" means 
(it doesn't show up in [1]) , but the sample sql for net2net-cert had 
kind=1 in the second child_config_traffic_selector.
