我在同时使用IPv4和IPv6的专用服务器上使用Debian Wheezy。
ifconfig eth0
eth0 Link encap:Ethernet HWaddr 11:11:11:11:11:11 inet adr:90.0.0.1 Bcast:90.0.0.255 Masque:255.255.255.0 adr inet6: fe80::21c:c0ff:feb9:829c/64 Scope:Lien adr inet6: 2001:a100:1:bbbb::1/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1544 errors:0 dropped:0 overruns:0 frame:0 TX packets:2199 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:304146 (297.0 KiB) TX bytes:1376282 (1.3 MiB) （几分钟后，RX下降计数器增加。）
猫/ etc / network / interfaces
我第一次使用“网关”关键字，但它没有工作，所以我试图在文件中添加路由，但它也没有工作。
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 90.0.0.1 netmask 255.255.255.0 network 90.0.0.0 broadcast 90.0.0.255 gateway 90.0.0.254 iface eth0 inet6 static address 2001:a100:1:bbbb::1 netmask 64 # gateway 2001:a100:1:bbff:ff:ff:ff:ff up ip -6 route add ::/0 via 2001:a100:1:bbff:ff:ff:ff:ff dev eth0 down ip -6 route del ::/0 via 2001:a100:1:bbff:ff:ff:ff:ff dev eth0
ip-6路由显示
这些是重新启动服务器几分钟后显示的路由。
2001:a100:1:bbbb::/64 dev eth0 proto kernel metric 256 2001:a100:1:bb00::/56 dev eth0 proto kernel metric 256 expires 2591959sec fe80::/64 dev eth0 proto kernel metric 256 default via fe80::224:c3ff:fe84:400 dev eth0 proto ra metric 1024 expires 1759sec default via fe80::224:c3ff:fe84:800 dev eth0 proto ra metric 1024 expires 1759sec
问题
为什么不考虑我的默认路由 （无论在启动时使用关键字gateway或ip -6 route add /etc/network/interfaces ？注意，如果我手动添加路由，它可以正常工作，我可以TX和RX互联网使用IPv6（问题是使其自动）。
那些奇怪的内核路由是什么，将会过期？ 我需要他们吗？ 我的服务器直接连接到同一个networking作为一个rooter（2001：a100：1：bbff：ff：ff：ff：ff），它本身直接连接到互联网。
