Two lines with the same ip destination in routing table

I am studing a particular case in routing table. As the title i have this table for a particular router in a net:

destin.IP       Mask             NextHop            Interface
193.14.5.160    255.255.255.0    ---.---.---.---    m0
193.14.5.192    255.255.255.0    ---.---.---.---    m1
111.0.0.0       255.0.0.0        ---.---.---.---    m0
192.16.7.0      255.255.255.0    111.15.17.32       m0
194.17.21.0     255.255.255.0    111.20.18.14       m0
194.17.21.16    255.255.255.0    111.20.18.14       m0
192.16.7.0      255.255.255.0    111.20.18.14       m0
194.17.21.0     255.255.255.0    111.15.17.32       m0
194.17.21.16    255.255.255.0    111.15.17.32       m0
0.0.0.0         0.0.0.0          111.30.31.18       m0

In that table there are lines with the same IP address like

192.16.7.0      255.255.255.0    111.15.17.32       m0

and

192.16.7.0      255.255.255.0    111.20.18.14       m0

in this case which of the two lines is chosen for routing? Why?

Thanks!

1What router / operating system is the routing done on? – user1686 – 2015-05-09T15:05:43.060

Sorry, this is either incomplete or just wrong. For one, the question doesn't mention Linux anywhere. (Even if guessing based on how the example table looks, it's most definitely not Linux nor BSD.) For another, even on Linux, this does not depend on loaded modules (which modules, by the way?) – identical routes have an explicit preference setting (the route metric), and 'load sharing' only happens if an explicit multi-gateway route is created. – user1686 – 2015-05-09T15:04:15.137
