thank you david for helping me in this issue, i attached to you a picture of the network diagram that i did in my lab, also with some show commands from juniper, i checked the ospf database but i cant see 2 routes on juniper, this is the same design as the customer, forget the load balancing, i created the loopback interfaces acting like the networks connected to the router, if you notice that 10.1.1.1 is only through one road and nothing in OSPF database..
