+\begin{itemize}
+    \item Everything is \gls{tlv} based. Making the protocol very extensible by standardizing new \gls{tlv} values.
+    \item The participating nodes communicates with its neighbors on \gls{l2}. Thereby not \textit{requiring} \gls{l3} addresses on the link. And instead uses the \gls{mac} to target the neighbor node.
+    \item The connection is done on per-interface. Similar to \gls{ospf3}. Instead of the global approach in \gls{ospf2}.
+    \begin{itemize}
+        \item The per-interface is the result of deciding the area is handled per-interface. Instead of at the per-node level.
+        \item The border between areas is at the node level. Instead of the interface level in \gls{ospf2}.
