I have one ISP who provides me with multiple links, to allow me to loadshare I use BGP with metrics, this allows BGP to pick the best routes out and our architects to decide inbound balencing across our IP range. here is an example config. hope it helps.

router bgp XXXXX

network x.x.x.x mask 255.255.240.0
