I have observed that flood towards tunnels that are referenced via unknown-dst is done only to the first destination

       for tunnel in self.unknown_dsts:
            port_no = self.tunnels[tunnel][0]

        ovs_ofctl("add-flow %s table=1,priority=0,action=%s"
                  % (self.short_name, ",".join(flood_ports)))

Which prevents from other tunnel destination from receiving  BUM's

Attached below a patch which forwards flood to all unknown-dsts
