CentOS 7中的IPv6配置选项是什么意思？

10

在CentOS上手动配置网络接口时（我正在尝试配置仅IPv6主机）以下设置的确切含义是什么？

我可以猜出其中一些名字的含义，但我不知道它们的含义（我的某些猜测可能是错误的）。这些配置选项是否有任何官方文档，我找不到任何文档？

从/ etc / sysconfig / network-scripts / ifcfg-eth0

IPV6INIT=yes          # I assume this just enables IPv6 networking on this interface?
IPV6_AUTOCONF=no      # Does this disable SLAAC?
IPV6_AUTOTUNNEL=no    # ?
IPV6_FAILURE_FATAL=no # Something to do with IPv6 not working not being an issue?
IPV6_DEFROUTE=yes     # ?
IPV6_PEERDNS=yes      # Does this mean we use the default gateway for DNS queries?
IPV6_PEERROUTES=yes   # Same as above?
IPV6ADDR=1::2/64      # This is obviously the IPv6 address and subnet mask
IPV6_DEFAULTGW=1::1   # This is obviously the default gateway

同样对于IPv4而言，设置DNS1和DNS2存在，是否等同于存在IPV6_DNS1和IPV6_DNS2存在？

感谢您提供的出色链接，尽管我真的很想知道我指定的那些IPv6选项的含义，而不是对其含义的链接，因为链接可能会遭受链接腐烂的困扰。

从：

IPV6ADDR             #<addr/mask> - Where address is the first static, or primary, IPv6 address on an interface. 
IPV6ADDR_SECONDARIES #<addr/mask> Option additional addresses .
IPV6_AUTOCONF        #<yes/no> - Enable IPv6 autoconf configuration for this interface (an IPv6 address will be requested using Neighbor Discovery (ND)).
IPV6_AUTOTUNNEL      #<yes/no> - Control IPv6 automatic tunneling (device sit0)
IPV6_DEFAULTGW       #<addr> - IPv6 default gateway
IPV6_DEFROUTE        #Does option even exist?
IPV6_FAILURE_FATAL   #<yes/no> - Whether the device is disabled if IPv6 configuration fails.
IPV6FORWARDING       #<yes/no>- Control IPv6 forwarding (box acting as router).
IPV6INIT             #<yes/no> - Initialize this interface for IPv6 addressing.
IPV6_MTU             #<integer> IPv6 MTU for this link.
IPV6_PEERDNS         #<yes/no> - Does this option exist? I assume it does the same as the IPv6 version?
IPV6_ROUTER          #<yes/no> - Control sending of router advertisements and isRouter on neigbor advertisements.


# defaults:
# IPV6_AUTOCONF=(see IPV6FORWARDING)
# IPV6_AUTOTUNNEL=no
# IPV6_FAILURE_FATAL=???
# IPV6FORWARDING=no
#  if IPV6FORWARDING=yes: IPV6_AUTOCONF=no, IPV6_ROUTER=yes
#  if IPV6FORWARDING=no:  IPV6_AUTOCONF=yes
# IPV6INIT=no
# IPV6_PEERDNS=???
# IPV6_ROUTER=(see IPV6FORWARDING)
