因此，我有一个运行radvd的Debian系统，它也有一个/etc/network/interfaces，而且由于某种原因，尽管配置上没有明显的差异，但只有我的wlan0接口有一个来自我分配的/64的IPv6地址，而不是eth0接口。

代码语言：javascript
运行
复制
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether b8:27:eb:96:8f:f0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.1/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::ba27:ebff:fe96:8ff0/64 scope link 
       valid_lft forever preferred_lft forever

4: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether b8:27:eb:c3:da:a5 brd ff:ff:ff:ff:ff:ff
    inet 192.168.84.1/24 brd 192.168.84.255 scope global wlan0
       valid_lft forever preferred_lft forever
    inet6 2001:XXXX:XXXX:XX81::1/64 scope global 
       valid_lft forever preferred_lft forever
    inet6 fe80::ba27:ebff:fec3:daa5/64 scope link 
       valid_lft forever preferred_lft forever

这是我的radvd.cond..。

代码语言：javascript

复制
interface eth0
{
        AdvSendAdvert on;
        prefix 2001:XXXX:XXXX:XX00::1/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

interface wlan0
{
        AdvSendAdvert on;
        prefix 2001:XXXX:XXXX:XX81::1/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

这是/etc/network/interfaces..。

        address 192.168.1.1

        address 2001:XXXX:XXXX:XX00::1/64

auto wlan0

iface wlan0 inet static
        address 192.168.84.1
        netmask 255.255.255.0
        up route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.1.1
        up route del -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.1.1
iface wlan0 inet6 static
        address 2001:XXXX:XXXX:XX81::1/64

allow-hotplug eth1
iface eth1 inet manual

最后我的sysctl -a值为wlan0和eth0..。

wlan0界面看起来很相似，尽管net.ipv6.conf.eth0.autoconf被设置为1，尽管我检查了它，而且它也肯定没有在sysctl.conf或sysctl.d中设置。

如果inet设置在ifupdown中失败，它们将阻止应用inet6设置。

当eth0第一次被提出来时，wlan0可能还没有并且没有IP配置。因此，通过wlan0 0‘S IP路由的额外设置(甚至可能不需要)不起作用。这使得eth0无法被提出来(从逻辑上:从ifupdown的角度来看)。它实际上是提出来的)，而inet6节并没有通过。

因此:删除所有额外的up route add/del条目。如果您真的不想删除它们，那么在每个命令的末尾添加一个额外的|| true (或2>/dev/null || :)，防止这些命令在整个设置中失败。
