IPSec route details

Ip sec adds two route entires for the same network.

for eg:

192.168.10.0 dev eth0
192.168.10.0 dev ipsec0

where eth0 is a phsical NIC and ipsec0 is a psuedo device..
My question is how do they differentiate between the route

i.e a packet with destination 192.168.10.1
which route will it take eth0 or ipsec0??

as far as my understanding it should see the first match but somehow i see
that the packet goes through the eth0 interface sometimes and sometimes
through ipsec0.

i want to know how do they make a switch i.e depending on what factor they
choose the route and how???

Thanks & Regards,
Lakshmi
