If you want to prevent a PE router from deciding which ingress packets to
drop, the only plan is to send packets to spoke sites at or below the spoke
line-rate. The only good way to do that is shaping on the hub router.
shape average 100000000 < --- 100Mbps parent shaper.
shape average 1536000
shape average 3072000
... whatever you typically use here....
