Thank you for your help and best regards. Netplan supports SIT, GRE, IP-in-IP (ipip, ipip6, ip6ip6), IP6GRE, VTI and VTI6 tunnels.

An 802.1Q VLAN switch is really a VLAN bridge, because 802.1Q as a standard just extends 802.1D (all devices that support 802.1Q must also support 802.1D). Technically, VLAN bridge is the correct terminology, but very few people would know what that means.
Netplan configuration files are written in YAML syntax with a.yaml file extension. To configure a network interface with Netplan, you need to create a YAML description for the interface, and Netplan will generate the required configuration files for the chosen renderer tool. Netplan supports two renderers, NetworkManager and Systemd-networkd.
NetPlan is a big change in the existing Ubuntu networking, but it is intended to simplify and create more flexible configurations. - docs: Fix example cloud-init analyze command to match output. [Wesley Gao] - netplan: Correctly render macaddress on a bonds and bridges when provided.
Overview NetworkManager includes basic Open vSwitch support, good enough to be capable of setting up simple Open vSwitch configurations. It is not extensive and does not expose all functionality of Open vSwitch provides. For large or complicated deployments users are advised to use native tools shipped with Open vSwitch.
Sep 15, 2020 · Each Netplan Yaml file starts with the network key that has at least two required elements. The first required element is the version of the network configuration format, and the second one is the device type. The device type can be ethernets, bonds, bridges, or vlans. The configuration above also has a line that shows the renderer type.
If your external network uses a VLAN, verify that the VLAN is assigned to the physical switch ports that the network nodes are connected to. If you have different networks for management and data, run this command to ensure that tunneling is set up correctly: powervc-config network tunneling-ip --set < ip_address > --node < node_name > --restart .
SI il protocollo 802.1Q, o meglio le VLAN sono possibili, anche se francamente non le ho mai utilizzate in un server, l’unica possibilità, ovvero un firewall, di solito ho sempre utilizzato prodotti dedicati. Comunque appena riesco faccio un mini lab per fare due test.

Netplan configuration files are stored in the /etc/netplan directory and have the extension .yaml. You’ll probably find one or two YAML files in this directory.

trying to set up a fixed IP address on one of two NIC. I try using netplan. Not working at all. Not an expert on this, I am out of my wits and ready to roll back to some other way (networkd).
There are plenty of guides out there for making ethernet bridges in Linux to support virtual machines using built-in network scripts or NetworkManager.

Dec 24, 2019 · Playing around with Ubuntu’s new network configuration tool NetPlan, I was able to create multiple VLANs off a single interface eno1. I set the default gateway to be eno1.10 , while the other VLANs did not require an IP address (although you could add one if you like): 利用する予定のVLAN IDをtrunkに設定しておかないと、スイッチがパケットを通してくれません。タグなし(untag)パケットはネイティブVLANに疎通します。 Ubuntu17以降、netplanの場合は、特に追加のインストールをすることなくVLANを構成できます。

Use macvlan networks. Estimated reading time: 3 minutes. Some applications, especially legacy applications or applications which monitor network traffic, expect to be directly connected to the physical network.

Use the default, which is VLAN isolation method on a single physical nic (on the host) that will carry all traffic types (management, public, guest etc). Note: If you’ve iproute2 installed and host’s physical NIC MTUs configured, you can used VXLAN as well.
