no need to set static-routes. your interface config do these settings in
/etc/sysconf/network-scripts/ifup-routes automatic.

with your settings in static-routes you have double entries in the
output from /sbin/route.

the correct entrys from /sbin/route -n would be somethink like this:
10.1.1.0     0.0.0.0  255.255.255.0   U     0      0        0 eth0
192.168.0.0  0.0.0.0  255.255.0.0     U     0      0        0 eth1
127.0.0.0    0.0.0.0  255.0.0.0       U     0      0        0 lo
0.0.0.0      10.1.1.1 0.0.0.0         UG    0      0        0 eth0
