The OS is supposed to choose a "functional" address, which when paired 
with a routing entry, makes the destination reachable.  However, in a 
multi-homed environment this may not choose the desired connection (does 
not account for bandwidth, latency, hops, etc).  Few applications

There are also several situations in which the backup servers or clients 
may use additional IPs to establish network presence on a 
service-by-service basis (i.e. all bacula/backup traffic moves over one 
IP address, all web traffic over another IP address, all SSH/mgmnt over 
another address, etc etc).

There was a big discussion about this some time ago which you may read:
