Linux - Network Bonding

Just as its name indicates, network bonding is a technique to bond a plurality of network interface together for load balance and a wider bandwidth.

The configuration of network bonding is simple. Taking ArchLinux for instance, the network bonding of 2 network interfaces (e.g., eth0 and eth1) can be configured as follows.

• /etc/systemd/network/10-bond0-eth0.network

  [Match]
  Name=eth0
  
  [Network]
  Bond=bond0
  

• /etc/systemd/network/10-bond0-eth1.network

  [Match]
  Name=eth1
  
  [Network]
  Bond=bond0
  

• /etc/systemd/network/10-bond0.netdev

  [NetDev]
  Name=bond0
  Kind=bond
  
  [Bond]
  Mode=802.3ad
  LACPTransmitRate=fast
  MIIMonitorSec=100ms
  

• /etc/systemd/network/10-bond0.network

  [Match]
  Name=bond0
  
  [Network]
  Address=xxx.xxx.xxx.xxx/24
  Gateway=xxx.xxx.xxx.xxx
  DNS=xxx.xxx.xxx.xxx
