I want to ensure that all IP traffic going to 172.16.60.62 uses eth6. Please provide complete commands because my linux-fu is rusty. The host is running Ubuntu Precise 12.04

user@host:~$ ifconfig eth3
eth3      Link encap:Ethernet  HWaddr 00:e0:81:72:fe:c9  
          inet addr:172.16.60.122  Bcast:172.16.60.255  Mask:255.255.255.0
