2 days ago VRRP is not supported on a VLAN interface with a user-configured MAC address. Linux, FreeBSD, Mac OS X¶ The dd command is the easiest way to erase the partition table from the USB memstick on UNIX and UNIX-like operating systems such as Linux, FreeBSD, and OS X. Advance skill on Switching (VLAN, VTP, Spanning Tree, RSTP, MST). The VLAN-aware mode in Cumulus Linux implements a configuration model for large-scale layer 2 environments, with one single instance of spanning tree protocol. Each physical bridge member port is configured with the list of allowed VLANs as well as its port VLAN ID, either primary VLAN Identifier (PVID) or native VLAN. MAC address learning.
Some applications, especially legacy applications or applications which monitornetwork traffic, expect to be directly connected to the physical network. Inthis type of situation, you can use the macvlan
network driver to assign a MACaddress to each container’s virtual network interface, making it appear to bea physical network interface directly connected to the physical network. In thiscase, you need to designate a physical interface on your Docker host to use forthe macvlan
, as well as the subnet and gateway of the macvlan
. You can evenisolate your macvlan
networks using different physical network interfaces.Keep the following things in mind:
It is very easy to unintentionally damage your network due to IP addressexhaustion or to “VLAN spread”, which is a situation in which you have aninappropriately large number of unique MAC addresses in your network.
Your networking equipment needs to be able to handle “promiscuous mode”,where one physical interface can be assigned multiple MAC addresses.
If your application can work using a bridge (on a single Docker host) oroverlay (to communicate across multiple Docker hosts), these solutions may bebetter in the long term.
Create a macvlan network
When you create a macvlan
network, it can either be in bridge mode or 802.1qtrunk bridge mode.
In bridge mode,
macvlan
traffic goes through a physical device on the host.In 802.1q trunk bridge mode, traffic goes through an 802.1q sub-interfacewhich Docker creates on the fly. This allows you to control routing andfiltering at a more granular level.
Bridge mode
To create a macvlan
network which bridges with a given physical networkinterface, use --driver macvlan
with the docker network create
command. Youalso need to specify the parent
, which is the interface the traffic willphysically go through on the Docker host.
If you need to exclude IP addresses from being used in the macvlan
network, suchas when a given IP address is already in use, use --aux-addresses
:
802.1q trunk bridge mode

If you specify a parent
interface name with a dot included, such as eth0.50
,Docker interprets that as a sub-interface of eth0
and creates the sub-interfaceautomatically.
Use an ipvlan instead of macvlan
In the above example, you are still using a L3 bridge. You can use ipvlan
instead, and get an L2 bridge. Specify -o ipvlan_mode=l2
.
Use IPv6
If you have configured the Docker daemon to allow IPv6,you can use dual-stack IPv4/IPv6 macvlan
networks.
