 4. Consider the network below in which a stub domain, `AS456`, is connected to two providers `AS123` and `AS789`. `AS456` advertises its prefix to both its providers. On the other hand, `AS123` advertises ``2001:db8:dead::/48`` while `AS789` advertises ``2001:db8:beef::/48`` and ``2001:db8:dead:cafe::/63``. Via which provider will the packets destined to ``2001:db8:dead:cafe::1`` will be received by `AS456` ?

 5. Consider that the AS stub (`AS456`) shown in the figure below decides to advertise two ``/48`` prefixes instead of its allocated ``/47`` prefix.

 6. Consider the network shown below. In this network, the metric of each link is set to `1` except link `A-B` whose metric is set to `4` in both directions. In this network, there are two paths with the same cost between `D` and `C`. Old routers would randomly select one of these equal cost paths and install it in their forwarding table. Recent routers are able to use up to `N` equal cost paths towards the same destination.
