ip link set br0 up
 
ip link set enp0s8 up
#ip addr flush enp0s8
ip link set enp0s8 master br0

Affichage et configuration 

bridge link
bridge fdb show dev br0
bridge vlan show
 
ip addr add dev br0 192.168.56.11/24

Supression 

ip addr flush br0
ip link set enp0s8 nomaster
#ip link set enp0s8 down
ip link del br0 type bridge

nmcli

nmcli connection add type bridge autoconnect yes con-name br0 ifname br0
nmcli con show
nmcli -f bridge con show br0

Disable STP 

sudo nmcli con modify br0 bridge.stp no

Afficher la conf 

nmcli con show
nmcli -f bridge con show br0

Pour ajouter, ou pour mettre une interface en esclavage 

nmcli con add type bridge-slave ifname team0 master br0

RedHat

     Edit /etc/sysconfig/network-scripts/ifcfg-eth0
        comment out BOOTPROTO
        Add BRIDGE=br0
    Create /etc/sysconfig/network-scripts/ifcfg-br0
        The content should be:

DEVICE=br0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Bridge
