squid load shareing

[lasa]

I am having two Internet public static IPs for Internet ( actually they are
DSL lines). My squid is configured to give all internal LAN Internet
requests to one DSL static IP through one NIC and this is working fine. If I
need to add the second IP address to the squid machine How can I do this? I
tried to add that interface in normal way as ifcfg-eth2. I don't know
weather the load is shared or not among those two interfaces. Let me know
how to do this in standard way?
