 \section{EIGRP}
 
-\gls{eigrp} is Cisco's enhanced edition if \gls{igrp}. Dating back to 1993 and a leg for Cisco over other vendors back in the early days of the Internet. (.. hmm. And remember Cisco's implementation of \gls{ospf} was known to be unstable until the early 2000's.)

-The change to \gls{eigrp} from \gls{igrp} was due to the support of classless routing. (\gls{igrp} only supported classful routing of class A (/8), B (/16), and C (/24) networks.)

-\gls{eigrp} adds support for \gls{vlsm} and the \gls{dual} with improved routing capabilities in comparison to \gls{igrp}. Overall \gls{eigrp} provides better capabilities compared to it's predecessor.

 \subsection[Math]{The Math behind}

-By default $K_2$, and $K_4$ is set to zero. (The are user customizable!) And $K_5$ is set to 0.

 In effect the resulting shorter formula is this:
 
-\fig{math/eigrp-dual-short}{eigrp-dual-short}{\glspl{eigrp} \gls{dual} short formula}

+    formula}
 
 \subsection{How it actually works}
 
-\gls{eigrp} does it routing on a \texttt{next-hop} basis. Meaning it only stores information about a given routes next turn. And \textbf{not} about the destination itself. (Like \gls{ospf} does)
