Routage¶

Coté Adhérent-e :

# 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...

Et coté routeur :

# 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
