This feature (Policy Map) is not introduced in 16.1. It was introduce in
14.2.

I know because I requested this feature and was personally responsible
for working with them to introduce it.

We use it, and it works perfectly. We are on 14.2R6.5. I highly
recommend it; far better than Juniper's old-style rewriting on egress.
