OSPFv2 does not support unequal-cost load balancing. Well, there is a way to do that; For example A customer have three E1's to a remote site. Two are p-t-p and the other channel off of a E3. When you add E3; EIGRP choose E3, ignoring the other two E1's. Using the variance command you force EIGRP (Cisco) to utilize all three E1's.
And now you could tune the OSPF metrics so that three paths would appear equal (as Farhan pointed out) or you could use RIP, assuming that the hop count to reach the destination on both links is the same. In either case you still have equal cost load balancing on two unequal links, which will result in wasted bandwidth at best and a bottleneck at worst.

EIGRP supports this behavior by variance factor. If EIGRP is open atandard (not Cisco proprietry) then Juniper will also support the same feature for EIGRP. However you can use some tricks to justify your scenario.
