## 创建桥接连接
nmcli connection add type bridge ifname br0 con-name br0
 
## 添加网络接口到桥接连接
nmcli connection add type bridge-slave ifname enp1s0 master br0
nmcli connection add type bridge-slave ifname enp2s0 master br0
nmcli connection add type bridge-slave ifname enp3s0 master br0
nmcli connection add type bridge-slave ifname enp4s0 master br0
nmcli connection add type bridge-slave ifname enp5s0 master br0
nmcli connection add type bridge-slave ifname enp6s0 master br0
nmcli connection add type bridge-slave ifname enp7s0 master br0
nmcli connection add type bridge-slave ifname enp8s0 master br0
 
 
## 配置桥接连接的IPv4地址
# nmcli connection modify br0 ipv4.method manual ipv4.address 192.168.60.100/24
# nmcli connection modify br0 ipv4.addresses "192.168.100.26/24"
# nmcli connection modify br0 ipv4.gateway 192.168.100.2
# nmcli connection modify br0 ipv4.dns 8.8.8.8
 
## 设置IP地址:192.168.13.166
nmcli connection modify br0 ipv4.method manual ipv4.address 192.168.13.166/24 ipv4.gateway 192.168.13.1
## 添加IP地址：192.168.3.166
nmcli con mod br0 +ipv4.addresses "192.168.3.166/24"
 
# 重新加载连接
nmcli connection reload
 
# 启用桥接连接
nmcli connection up br0
systemctl restart network
 
## 删除桥接
nmcli connection delete br0
``

```bash
## 安装bridge-utils
apt-get install bridge-utils
yum instakk -y bridge-utils
 
## 创建桥接设备： 使用brctl命令创建一个桥接设备。假设你要创建一个名为br0的桥接设备，可以使用以下命令：
brctl addbr br0
 
## 将网络接口添加到桥接设备： 将要桥接的网络接口（网卡）添加到新创建的桥接设备中。例如，假设你有两个网卡eth0和eth1，可以使用以下命令：
brctl addif br0 eth0
brctl addif br0 eth1
 
## 激活桥接设备： 使用以下命令激活桥接设备：
ifconfig br0 up
 
## 配置IP地址： 为桥接设备分配一个IP地址。例如：
ifconfig br0 192.168.16.100 netmask 255.255.255.0
 
## 禁用原始网络接口： 如果你希望通过桥接设备来处理网络流量，可以禁用原始网络接口。例如：
ifconfig eth0 down
ifconfig eth1 down
## 或者使用ip link set命令：
ip link set dev eth0 down
ip link set dev eth1 down
