Only shows the local-rib. I have struggled with this lack of visibility
into post processed rib-outs in Cisco before. Juniper shows it nicely
(shameless plug)
AS-path prepends and AS-paths of locally generated routes are also not
shown (can make it tough to see AS-Paths in aggregate routes that you make
in your own AS)
