"tableid" in debug ip packet

Dear All,
            Anyone know what is the tableid=0 represents in the debug ip
packet ?

Here is the output of debug ip packet

*Aug 4 12:20:35.150: IP: *tableid=3*, s=6.6.6.3 (local), d=6.6.6.6
(Tunnel1), routed via FIB

sending

*Aug 4 12:20:35.294: IP: s=6.6.6.6 (Tunnel1), d=6.6.6.3 (Tunnel1), len 100,
rcvd 3

I think it may be related to VRFs ?
