Step1. Enable IPv6 forwarding for Kernel via /etc/sysctl.conf:
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.default.forwarding = 1
net.ipv6.conf.br0.forwarding = 1
net.ipv6.conf.br1.forwarding = 1
net.ipv6.conf.br2.forwarding = 1
Step2. Use radvd be a DHCPv6 Server:
Step2.1 Open then edit /etc/radvd.conf:interface br0
{
AdvSendAdvert on;
MinRtrAdvInterval 30;
MaxRtrAdvInterval 100;
prefix 3001:688::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
interface br1
{
AdvSendAdvert on;
MinRtrAdvInterval 30;
MaxRtrAdvInterval 100;
prefix 3001:588::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
interface br2
{
AdvSendAdvert on;
MinRtrAdvInterval 30;
MaxRtrAdvInterval 100;
prefix 3001:288::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
Step2.2: Launch radvd immediately as well as start running it when system boots up:[root@rhel7 network-scripts]# systemctl start radvd
[root@rhel7 network-scripts]# systemctl enable radvd
[root@rhel7 network-scripts]# systemctl status radvd
