斯巴达DD后怎么开启IPV6 啊

先安装了 debian9 默认带ipv6 配置如下
cat /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 45.154.214.17 netmask 255.255.255.0 gateway 45.154.214.1 iface eth0 inet6 static         accept_ra 0         address 2604:9cc0:0000:5a00:0000:0000:0000:0001         netmask 64 post-up /sbin/ip -r route add 2604:9cc0::1 dev eth0 post-up /sbin/ip -r route add default via 2604:9cc0::1 复制代码

然后dd后  网卡变成ens3 遂修改为
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto ens3 iface ens3 inet static address 45.154.214.17 netmask 255.255.255.0 gateway 45.154.214.1 iface ens3 inet6 static         accept_ra 0         address 2604:9cc0:0000:5a00:0000:0000:0000:0001         netmask 64 post-up /sbin/ip -r route add 2604:9cc0::1 dev ens3 post-up /sbin/ip -r route add default via 2604:9cc0::1复制代码

然后重启网络  systemctl restart networking.service

却报错

Job for networking.service failed because the control process exited with error code.
See “systemctl status networking.service” and “journalctl -xe” for details.

我哪一步做错了啊

吉林省网友说：没有问题，reboot就可以了

江苏省网友说：老哥牛逼 reboot之后确实好了

为啥重启网络报仇  重启还能成功啊
