0.0.0.0         192.168.100.1   0.0.0.0         UG        0 0          0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0
192.168.100.0   0.0.0.0         255.255.255.0   U         0 0          0 eth0


You should have all 3 lines - a default route, a link local route, and a local subnet route.
