Furthermore, starting with RouterOS 7.7, it is also possible to create a RAM disk where a part of the main memory can be used as data storage.įor all those who can't/won't build the container themselves, I have prepared three ready-made container images that you can download here: only has 16MB Flash but owns a USB port, the root directory of the container can also be placed on it. RAM: For reasonable operation, a recommend using a router with at least 128MB of RAM.įile-Storage: The container itself uses between 10 -15MB when extracted to the filesystem. and any hardware which can run the x86 variant of RouterOS.netPower 15FR / netPower 16P / FiberBox Plus / netFiber 9.

That would be the following models (excerpt, without claim to completeness) In the instructions and the Mikrotik script I assume that you run a current VLAN setup via 'VLAN filtering' in a VLAN bridge, like shows in his instructions Mikrotik VLAN Konfiguration ab RouterOS Version 6.41 on this board.Ĭompatibility/Availability of the Container-Package on Mikrotik routersĪt the time of writing, the container feature of Mikrotik is limited to these platforms I also provide a Mikrotik script which automates the complete interface setup and container creation.

I extended the container in the sense that VLANs can be changed easily via an environment variable on the Mikrotik. The container is based on a small Alpine Linux and the repeating is done by a C programmed daemon from Darell Tan. This enables the cross VLAN announcement of many devices which normally only announce themselves in their own layer-2 broadcast domain using the mDNS link local multicast address 224.0.0.251 via UDP port 5353. However, since a Docker package for RouterOS 7 has been available for some time, I have built a Docker image based on the template of this Github Repo which runs directly on the router and reflects mDNS multicast packets between two or more VLANs. MDNS repeating (Multicast DNS) on Mikrotik routers, a feature often requested, is not yet part of RouterOS itself at the time of writing ( But Mikrotik is currently working on it).
