Create Bonding, Vlan, Bridge Interface in Ubuntu 18 Using Netplan and networkd
2 min readJul 19, 2020
Recently, my client has requested to make a host setup with network bonding, vlan, and bridge interface configurations. In the host the KVM / QEMU hypervisor is planned to be installed.
The following are some sample configurations that can be applied to netplan using networkd as its renderer. I also included several configurations from the netplan website.
Of course, the configuration below can be adjusted to the desired needs or conditions, hopefully it can help.
