Asking because I find it funny that that router is called “Cloud Core Router” but seemingly is totally ignorant of any of the new Networking Standards being developped by both MS and Cisco to replace VLAN’s in - ah - you know - a Cloud. Notable MS usage in Hyper-V since Server 2012 to use NVGRE to Isolate tenants and Cisco’s competing VXLAN.
I personally would have use coming in the next Revision of our own - ah - cloud - for my core router to actually work with the cloud to I It solate Network traffic of different tenants. Would be very wonderfull if I could map a port to a NVGRE Header and it then is just part of the MS Hyper-V cloud. It just happens I have to have a physical Cisco Router for a Logical and physical subnet (I.e. it Needs a public IP, then internally maps to a Logical Network that contains both, certain physical ports (for real Hardware) as well as - a Hyper-V Logical Network (for virtual machines that talk to both the Switch and the physical Hardware).
Life would be so much easier if the Cloud Core Router would live up to the Name.
In case MIkrotik wants their Cloud Core Router to be able to work in the core of a cloud - there is more Information about both Standards at
