On Mikrotik, if you put vlan 40, say, on interface 1, 2, 3, 4 and 5, but don’t actually bridge any of them together, or trunk them on layer 2, they’ll never see each other.

AFAIK, the VLANs on one port are not connected to the VLANs on another port. In other words, each VLAN is like a new port. You could then bridge ether1-VLANxyz to ether2-VLANxyz if you were so inclined. bp <part15sbs{at}gmail{dot}com> On 7/6/2015 9:12 AM, That One Guy /sarcasm wrote: Will I break the internet of things of I reuse the same vlan ID on multiple ports This is solely for simplified deployment of site routers since it turns out I need my OSPF subnets on vlans so I dont have to keep track of a billion vlan IDs as well as a billion /30s The ports would not be bridged, just share a VLAN ID I assume this is a big No No, more curious on the impact of doing so -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
