ipv6网络设置

ipv6网络的管理
建立ipv6地址
[root@localhost Desktop]# nmcli connection add con-name westos ifname eth0 type ethernet ip6 2017::1/48
Connection 'westos' (84efb7eb-dd9b-4c1c-b4da-069648899056) successfully added.

[root@localhost Desktop]# ifconfig

有时会出现ipv4地址，若只想出现ipv6的ip:
[root@localhost Desktop]# vim /etc/sysconfig/network-scripts/ifcfg-westos
TYPE=Ethernet
BOOTPROTO=none     ######改为none
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6ADDR=2017::1/48
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=westos
UUID=84efb7eb-dd9b-4c1c-b4da-069648899056
DEVICE=eth0
ONBOOT=yes

[root@localhost Desktop]# systemctl restart network
[root@localhost Desktop]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

检测ipv6网络是否可通：
[root@localhost Desktop]# ping6 2017::1
PING 2017::1(2017::1) 56 data bytes
64 bytes from 2017::1: icmp_seq=1 ttl=64 time=0.060 ms
64 bytes from 2017::1: icmp_seq=2 ttl=64 time=0.084 ms
64 bytes from 2017::1: icmp_seq=3 ttl=64 time=0.070 ms
64 bytes from 2017::1: icmp_seq=4 ttl=64 time=0.078 ms
