I can understand this; However, if I see a path, I _should_ (in theory) be
able to reach the destination network.

I'm not sure why routing policy is even being brought up right now.

Note that hop 16 is a customer access router.

Also note that ISIs border is now responding with !X:

PBI seems to be fine, perhaps another border router?

Its interesting how it has suddenly gone from !A to !X.
