#网桥#
#实验前#
#一.配置#
[[email protected] ~]# vim /etc/sysconfig/network-scripts/ifcfg-enp0s25
DEVICE=enp0s25 ##设备名称
ONBOOT=yes ##开启服务设备自动**
BOOTPROTO=none ##网卡工作状态
BRIDGE=br0 ##网卡开启的网桥接口
[[email protected] ~]# vim /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.25.254.66
NETMASK=255.255.255.0
TYPE=Bridg ##网络接口类型是桥接
[[email protected] ~]# systemctl stop NetworkManager.service
[[email protected] ~]# systemctl restart network
[[email protected] ~]# systemctl start NetworkManager.service
[[email protected] ~]# ifconfig
【测试】
[[email protected] ~]# virt-manager
--安装虚拟机
--Network install(HTTP,FTP,or NFS)
--URL:yum源
--Forward *3
--Finish
#二.命令管理方式#
##实验前删除和之前配置的team0
[[email protected] Desktop]# nmcli connection delete time0
[[email protected] Desktop]# nmcli connection delete eth0
[[email protected] Desktop]# nmcli connection delete eth1
#1.添加#
[[email protected] Desktop]# systemctl stop NetworkManager
[[email protected] Desktop]# brctl show
[[email protected] Desktop]# brctl addbr br0
[[email protected] Desktop]# brctl addif br0 eth0
[[email protected] Desktop]# ifconfig eth0 up
[[email protected] Desktop]# ifconfig br0 172.25.254.129 netmask 255.255.255.0
[[email protected] Desktop]# brctl show
[[email protected] Desktop]# ping 172.25.254.66
#2.删除#
[[email protected] Desktop]# ifconfig br0 down
[[email protected] Desktop]# brctl delif br0 eth0
[[email protected] Desktop]# brctl delbf br0
[[email protected] Desktop]# brctl show
#ipv6(Internet Proto version 6)#
#一.概述#
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
128/2 ---> 128/8 -> 16 ---> （IP地址表达）0-f
eg：2017：0：0：0：f：0：0：1/48
#二.配置#
[[email protected] Desktop]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.25.254.129
NETMASK=255.255.255.0
IPV6INIT=yes ##ipv6功能开启
IPV6_AUTOCONF=no ##IP为静止的
IPV6ADDR=2017:：e:f/64 ##设置的IP
#三.测试#
