bgp sorted tables

Hello, I'm trying to use sorted table feature (despite it is described as a little bit slower) I'm trying on 1.6.3, 1.6.4 with table master sorted; also on 2.0.2 format ipv4 table master4 sorted; But is does not seem to work, when show route from birdc routes are still in random order. anyone help on that, is this sorting still working ? Thanks in advance. Milen Bogunski
