网桥、ipv6的基本设置

1.网桥

配置

[root@foundation19 network-scripts]# vim ifcfg-enp0s25
DEVICE=enp0s25 ##设备名称
BOOTPROTO=none ##网卡工作状态
BRIDGE=br0 ##网卡开启的网桥接口
ONBOOT=yes ##开启服务设备自动激活
[root@foundation19 network-scripts]# vim ifcfg-br0
DEVICE=br0
ONBOOT=yes
BOOTPROTO=none
IPADDR0=172.25.254.19
NETMASK=255.255.255.0
TYPE=Bridge ##网络接口类型是桥接
[root@foundation19 network-scripts]# systemctl stop NetworkManager
[root@foundation19 network-scripts]# systemctl restart network
[root@foundation19 network-scripts]# systemctl start NetworkManager

命令管理方式

添加
systemctl stop NetworkManager
brctl show
brctl addbr br0
brctl addif br0 eth0
ifconfig eth0 up
ifconfig br0 172.25.254.219 netmask 255.255.255.0
brctl show
systemctl start NetworkManager
ping 172.25.254.250
删除
ifconfig br0 down
brctl delif br0 eth0
brctl delbr br0
brctl show

2.ipv6
internet proto version 6
ipv4 32/2 地址枯竭 子网掩码24 16 8
ipv6 128/2 子网掩码16 32 48 64 80
2017:0:0:0:f:0:0:1/48
2017::f:0:0:1
2017:0:0:0:f::1
0000——>ffff

配置

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.25.254.219
NETMASK=255.255.255.0
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6ADDR=2017::a:2/64
[root@localhost ~]# systemctl restart network

测试

[root@localhost ~]# ping6 2017::a:1
