#IPv6 confusion: can a router advertise that there's a #network on the other side? Without handing out any addresses?
I want to join 2 ULAs on 2 separate links: A/64 and B/64. The host routes between links and has A:1/64 and B:1/64.
This host is *not* the default router, so I can't set up the routes there and call it a day.
Is there a way?
