\textbf{An IPv4 interface} never announces v4-over-v6 routes
\textbf{Interface with v4 address:} no changes; just as unextended babel.

\textbf{A v6-only interface}
\textbf{Interface with only v6 addresses:}
\begin{itemize}
\item{} \alert{Installs a v4 route} nevertheless when receiving it
\item{} \alert{Announces a v4-over-v6 route} for each v4 route
\item{} \alert{Receiving} a v4 route: \alert{install it anyway}, the
router's address is irrelevant.
\item{} \alert{Announcing} a v4 route: use \alert{v4-over-v6}; we need
a next-hop and only have v6 at hand.

\begin{frame}{To sum up}
\begin{frame}{Conclusion}
\begin{itemize}
\item While routing, next-hop address is \alert{only useful to get layer 2
address}
\item New type of route: \alert{v4-over-v6}, v4 destination, v6 next-hop
\item Less network configuration, same features! Yay!
\item We have \alert{an extension draft} and \alert{an implementation}
\item Route IPv4 over an IPv6 network core. \textit{Look, Ma! No tunnels!}
\item Protocol \alert{described and drafted}
\item \alert{Production-ready implementation} available on the babeld
repository
\end{itemize}

\item \textbf{Intended status: \alert{experimental}}
\item Opinions: should it be adopted by workgroup or carried alone?
