Coté Adhérent-e :

<pre>

# IPv4 Adherent

ip addr add IP/32 dev eth0

ip route add default via 91.224.148.0 dev eth0 onlink

# IPv6 adherent

ip -6 addr add fe80::XX:YY/64 dev eth0

ip -6 route add default via fe80::31 dev eth0

ip -6 addr add IP/NN...

</pre>

Et coté routeur :

<pre>

# IPv4 routeur

ip addr add 91.224.148.0/32 dev lo 

ip route add IP/32 dev eth0.NNN

# IPv6 routeur

ip -6 addr add fe80::31/64 dev eth0.NNN

ip route add IP/56 vi fe80:XX:YY dev eth0.NNN
