LARTC - Oct 2007 - unable to add routes to empty table

Hi all,

I am trying to add an alternative routing table to a machine running 
2.6.21.

If I do a ip route show table x, it tells me the table is empty, then 
when I try to add a route I get "RTNETLINK answers: File exists" Now I
always understood this as meaning that I am trying to add a duplicate 
route to a table, but since the table in question doesnt have any 
entries I am a bit confused as to why this is occurring.

Table x is listed in the rt_tables in case you where wondering.

Regards

Jeroen
