In a vrf-lite environment, RDs are local to the router, so you can pick
any (as long as it's unique on the router). you only need route-target
if you're running BGP on the node to leak routes from one VRF to
another.. doesn't look  like you're doing any leaking, so I don't think
you need any route-targets
