PTX and MX as LSR look inside pseudowire to see if it's IP (dangerous
guess to make for LSR), CSR/ASR9k does not. So PTX and MX LSR will
balance your pseudowire even without FAT. I've had no problem having
ASR9k LSR balancing FAT PWs.

However this is a bit of a sidebar, because the original problem is
about elephant flows, which FAT does not help with. But adaptive
balancing does.
