Route announcements can be scoped. See NO-EXPORT. Just because _you_ can't see the announcement doesn't mean others can't see the announcement along with the rest of the publically announced networks. > Maybe I'm being dense here, but I'm truly puzzled by this (other than > the "this is how our network works and we're not changing it" > argument). IP addresses are not just assigned so that one can connect to the public internet. There are lots of other valid reasons for addresses to be assigned. Go look them up. They are documented in RFC's and at the RIR's.
