For all test cases the following network settings on esprimo:

\subsection{Test 2: IPv6 egress}

Similar to the IPv4 setting before, just for IPv6.
|

|

Step 1: getting IP address values

Step 3: setting neighbor entries

\begin{verbatim}
|

nico@ESPRIMO-P956:~$ sudo ip -6 neigh add 2001:db8:42::6 lladdr f8:f2:1e:09:62:d0 dev enp2s0f1
|
||||

|
||||
\end{verbatim}
|
||||
|
||||
Step 4: generating test packets
|
||||
|
||||
\begin{verbatim}
|
||||
nico@ESPRIMO-P956:~$ ping6 -c2 2001:db8:42::6
|

|
