upc Connect Box

aka: Ziggo Connect Box, Unitymedia Connect Box, Compal CH7465LG-ZG

• IPv6 and Ziggo – part 2 (Cdp blog)

• rapid-commit is broken ("The Connect Box supports rapid-commit and responds directly with a DHCP6 REPLY message. However, the resulting prefix-delegation does not work – it looks like the route has not been installed.")
• delegated prefixes are not persistent – it's like dynamic IPv6. An abomination.
