Beyond the binary choice to advertise or not to advertise a given prefix via a given peer/upstream and/or any TE policies your peers/upstreams may support via community/attribute tagging, you've really no control over inbound traffic path selection. You can prepend, but whether other networks honor it or ignore it - or if they do honor it, *how* they honor it - is entirely beyond your control.
So, vendor marketing claims aside, the concept of 'load-balancing' inbound traffic isn't really a valid one.
The only actual path-selection control you have is over your outbound traffic, and that only for a single hop beyond your network, into each of your peers/upstreams. What happens after that is beyond your control, as well.
