Dom0 :
已建立好與 Server 連接的端點 (sit0、sit1)，另外有另外可以使用的網段，把他設定在 DomU 網路的共用接口

# ifconfig eth0 inet6 add 2001:470:f902::1/48

// radvd - Router Advertisement Daemon

# apt-get install radvd

# vi /etc/radvd.conf

interface eth0                #The interface used to send ADV                                                               
{
    AdvSendAdvert on;        #Enable Advertisements
    #AdvManagedFlag on;      #Enable Managed bit
    #AdvOtherConfigFlag on;  #Enable Other Configure bit
    MinRtrAdvInterval 3;     #Set min. interval to send adv.
    MaxRtrAdvInterval 10;    #Set max. interval to send adv.
    prefix 2001:470:f902::/48    #Prefix
    { 
        AdvOnLink on;        #Adv. Using Link Layer
        AdvAutonomous on;    #Autonomous Flag
        #AdvRouterAddr on;
    };
};

# /etc/init.d/radvd restart

# echo 1 > /proc/sys/net/ipv6/conf/all/forwarding

DomU :

# ifconfig eth0 inet6 add 2001:470:f902::2/48

# route -A inet6 add ::/0 dev eth0
# route -A inet6  // show ipv6 route

$ ping6 2001:470:f902::2/48 // gateway

$ ping6 2600::
