if your system has several IP addresses added as aliases on a single
interface/subnet, the routing table will provide the 'source' addresses
for outgoing communications.
if for example you have 4 IP addresses assigned as follows
eth0 192.168.2.1
eth0:1 192.168.2.2
eth0:2 192.168.2.3
eth0:3 192.168.2.4
Then the routing table will work as:
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0
the source will be 192.168.2.1
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0:1
the source will be 192.168.2.2
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0:2
the source will be 192.168.2.3
etc.
