Tôi cố gắng định cấu hình cấu hình IPv4 & IPv6 tĩnh trên CentOS 6.2.
Cấu hình dưới đây hoạt động hoàn hảo:
# ifconfig eth0 x.x.x.x/29
# route add defalt gw x.x.x.y
# ip addr add dev eth0 XXXX:C810:3001:D00::3/56
# ip -6 route add default XXXX:C810:3001:D00::1
Tuy nhiên, tôi muốn giữ cấu hình này sau khi khởi động lại.
Vì vậy, tôi đã thực hiện các cấu hình sau:
Kích hoạt IPv6
[root@test network-scripts]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=test.net
NETWORKING_IPV6=yes
Cấu hình giao diện
[root@test network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="static"
ONBOOT="yes"
HWADDR="2C:C3:AC:A8:C3:3E"
IPADDR=x.x.x.x
GATEWAY=x.x.x.x
NETMASK=255.255.255.248
TYPE=Ethernet
IPV6INIT=yes
IPV6ADDR=XXXX:C810:3001:D00::3/56
IPV6_DEFAULTGW=XXXX:C810:3001:D00::1
DNS1=208.67.222.222
DNS2=208.67.220.220
# Only DNS{1,2} according to /usr/share/doc/initscripts-9.03.27/sysconfig.txt
# DNS3=2620:0:ccc::2
# DNS4=2620:0:ccD::2

Địa chỉ IPv6 của các trình phân giải thậm chí không có trong độ phân giải!
Tôi đã bỏ lỡ một bước cấu hình?
Tôi nghĩ rằng cấu hình IPv6 sẽ là một hình thức ..
