OK, I found it right after I sent this.  There is a sysctl switch called (off by default) that enables it.

My understanding is that when a router knows a route to an ip address, it is 
supposed to respond to arp who-has messages with an arp reply message giving 
its own mac address.  The fbsd router is not responding even though it has a 
correct route, has ip forwarding enabled and is seeing the arp who-has 
messages.  Shouldn't it be?
