Apologies if this is obvious, it wasn't to me when I started.  What I
did was: 

*) edit /etc/rtadvd.conf and added a line for "de1" (my "inside"
   interface) modeled after the ef0 example in the sample file.  I
   used address fec0:: . This should go on the main router if you have
   one.
   
*) on the router   
	sysctl -w net.inet6.ip6.forwarding=1
	sysctl -w net.inet6.ip6.accept_rtadv=0

*) on the clients:
   	sysctl -w net.inet6.ip6.forwarding=0
	sysctl -w net.inet6.ip6.accept_rtadv=1
   
*) start rtadvd on the router.

*) run rtsol on all the machines.  This will set an alias address for
   the interfaces and setup a default route pointing to the router.
   
   I cheated and ran this on the router too.  I didn't want to set the
   alias address by hand and have to duplicate the rtadvd.conf config
   line in a different file. I temporarily turned on accept_rtadv as such: 
   
   	sysctl -w net.inet6.ip6.accept_rtadv=1
	rtsol de1
      	sysctl -w net.inet6.ip6.accept_rtadv=0

   (What is the "approved" way of doing this???)

*) Now one should be able to ping the fec0:: address of all the ipv6
   hosts.  I've got 4 netbsd/i386 ipv6 machines here and they all ping
   and I can ssh-ipv6 to all the ipv6 addresses.
