Metro Ethernet Notes: http://www.experts-exchange.com/Hardware/Networking_Hardware/Routers/Q_23688899.html

Example with Wireless: http://mum.mikrotik.com/presentations/CZ09/VLAN-Workshop-Prague-final.pdf

Great examples with CoS: http://wiki.mikrotik.com/wiki/Vlans_on_Mikrotik_environment

• VLAN = Broadcast Domain
• VLAN interfaces on MikroTik devices are “add tag on egress / remove tag from ingress”
• To be able to forward packets from access-ports to VLANs, we need bridges
• Ethernet MTU will increase up to 1522 bytes because of the added tag
  • The normal Ethernet MTU is up to 1518 bytes

• Access
  • An access port should be used only with untagged packets.
  • This kind of port is used to connect PCs to the switch.
• Trunk
  • A trunk port is capable of receiving and forwarding packets from multiple vlans.
  • This type of port is used to interconnect switches.
• Hybrid
  • A hybrid port is a special mode that allow untagged and tagged packets on the same port.
  • For example, you have a VoIP desk phone and you connect your PC to the phone and the phone to the switch.
  • We will have a VLAN for VoIP and untagged data for the PC.

• Create VLAN sub-interfaces on physical interfaces
• Bridge the sub-interfaces
  • To forward packets from access-ports to VLANs we need bridges
• IP addresses are then configured on the respective bridges
• Treat EoIP tunnel interfaces like physical interfaces
• If you are not stripping tags, you don't need to configure the VLAN interfaces, at least on physicsal trunk ports

1. Configure VLANs on trunk interface ports

   • /interface vlan add name=vlan-10 vlan-id=10 interface=ether5 disabled=no

2. Create bridges for the VLANs

   • /interface bridge add name=br-vlan10 disabled=no

3. Add access-ports to the bridges

   • /interface bridge port add interface="vlan-10" bridge="br-vlan10" disabled=no
     /interface bridge port add interface="ether1" bridge="br-vlan10" disabled=no
