load sharing over 2 t-1's

I have 2 t-1's in a router, I'm using static routes. How does the IOS decide which t-1 to send traffic over?

thanks,

The IOS will automatically load share over, up to 4, equal cost paths but at the session, rather than at the packet, level.

You can force it to load share on a per packet basis by disabling fast switching,

no ip route-cache

on the interface but this is not recommended as it will impact the router's performance.

thanks, I'm reading about all this as I go along, would CEF be of any value?

Yes, you want to run CEF... CEF will load share based on the source and destination addresses.
