It does nothing of this, *unless* you're also doing reverse-path filtering
on your external links (which is a dangerous thing in most cases anyway).

It breaks pinging / tracerouting *to* a specific router on its IXP
address, indeed, but not *through* the router, which is by far the
most common usage.
