A prefix is a prefix. A route is a prefix
plus a next-hop. Your next hop for your PNI is different than
your IX.
And for me, it doesn't matter as long as I am maintaining both my
public link sand PNI's properly.
If my peers are not, I'm happy to take the longer path to reach them
until they are sufficiently incentivized to fix that. At the very
least, there won't be packet loss :-).
