网桥

通过网桥可以将虚拟设备分成多组,虚拟连接到多个虚拟网桥上,起到隔离效果

软件包:bridge-utils

查看:brctl show
添加:brctl addbr br0
查看:brctl showmacs bro0
删除:brctl delbr br0
设备接入:brctl addif br0 eth0
设备接入:brctl addif br0 eth1

激活设备:ip link set br0 up//ifconfig br0 up

测试连通性

STP:生成树协议----避免网络风暴,产生回环,广播泛滥占用网络带宽
通过算法,避免回环

启用STP协议:brctl stp br0 on

使用nmcli创建网桥,写入配置文件
nmcli
nmcli con add type bridge con-name br0 ifname bro0 ipv4.address 192.168.179.100/24 ipv4.method manual
nmcli con add type bridge-slave con-name br0-eth0 ifname eth0 master br0
nmcli con add type bridge-slave con-name br0-eth1 ifname eth1 master br0
nmcli con up br0-eth0
nmcli con up br0-eth1
nmcli con up br0//ip link set br0 up//ifconfig br0 on
