Network Bridge SLES 15

Using Network Configuration Files for Persistent Changes​

First, create the bridge device configuration file. In this example, we create a bridge named br0External that uses eth0 as the physical device and is assigned the IP address 192.168.100.100/16. If the bridge will be configured using DHCP, set BOOTPROTO='dhcp' and omit the IPADDR setting.

  1. Edit file /etc/sysconfig/network/ifcfg-br0External
BOOTPROTO='static'
BRIDGE='yes'
BRIDGE_PORTS='eth0' 
STARTMODE='auto'
IPADDR='192.168.100.100/16'
BRIDGE_STP='off'

Next, modify the physical device, in this case eth0, so that it does not have an IP address.

  1. Edit file /etc/sysconfig/network/ifcfg-eth0
STARTMODE='auto'
BOOTPROTO='none'
  1. Apply the configuration by restarting the network service
sudo systemctl restart network
warning

If the node’s IP address changes after registration, its configuration must be updated in Cluster Wizard or Node Client.
