It is not clear exactly which types of devices
vnet1 are in your setup. There are a few types of virtual devices which can be useful to include in a bridge, some of which can be created using the
One kind of virtual devices is
veth which creates pairs of connected virtual Ethernet interfaces.
ip link add veth0 type veth peer name veth1
In this example
veth1 are arbitrary interface names that I came up with for the example. This method can for example be useful if you want to move one of the two interfaces to a different networking namespace.
Another kind of virtual interface is
vlan where you create a single virtual Ethernet interface attached to a specific 802.1q tag on a physical interface:
ip link add link eth0 name eth0.10 type vlan id 10
There is a man page with information about even more types of virtual interfaces which can be created with the
ip command. The name of the man page depends on which version you have installed, I have seen it named
ip-link or just
Additionally if you are using any virtualization there are virtual interfaces connecting host and VM. The specifics of those depend on the virtualization solution you are using.
