I believe your problem is that OpenBSD 5.7 does not accept router advertisements (RA) if IPv6 forwarding is enabled. Do you have IPv6 forwarding enabled? Before 5.7, acceptance of RA was controlled by a single flag which affected all interfaces. So accepting RA on a router was dangerous since RAs are not authenticated and change the routing tables. OpenBSD 5.7 moved to a AUTOCONF6 flag per interface. The second change you need, which is to accept RA with forwarding enabled, was committed after 5.7. So please try again with a -current snapshot which at the moment is pretty close to what 5.8 will be.
