The nodes have an interface on the vpn with an ipv6addr of
$PREFIX::xxyy/64, and a public bridge interface with an ipv6addr of
$PREFIX:xxyy::1/64, where $PREFIX is the /48 we are delegated by
HE.net, and xx and yy are the two bytes of ipv4 address we use on our
private 10.11.xx.yy network.  The olsr6d.conf includes an HNA6 of
$PREFIX:xxyy::/64.  The only thing that changes between
working/notworking is that I turn off the ipv6 olsrd.

Our olsr6d.conf looks like this, for our node that lives at 

   IpVersion 6

   LinkQualityFishEye 0

           $PREFIX:1201::    64

   Interface "br-pub" "ptp"

I'd be happy to capture a packet trace of one of the route collapse
events, if it would be helpful.
