RB1100 Vlan setup

RouterOS Beginner Basics

Hi,

New to vlans in a Mikrotik, We need to pass a Vlan from our upstream provider to a customer on one of our networks, Is this just a case of adding the vlan to the IN Interface and also the same Vlan to the OUT Interface on a mikrotik for it to pass vlan traffic? Or will be need to bridge the two instances of the Vlan on the RB1100?

Eg,

eth1 > New Int vlan 100
eth10 > New Int vlan 100

There’s a couple of ways you can create vlans on an RB1100

  1. Involves just creating the vlans as you’ve mentioned above then adding them to a bridge group (this will ensure traffic coming in one will pass out over the other).
  2. If you’re using 2 ports in the same switch group you can vlan them there, removing the load from the router CPU and allowing traffic to pass at wire speed.
    2a. Same as 2 only if you want to be able to manage the traffic from those vlans you can force traffic to pass back up to the router CPU to be processed in the firewall.

There’s more information and an example on the mikrotik wiki here: http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features#Example_-_802.1Q_Trunking_with_Atheros_8316

Ok so Adding them in the Switch group will make them Access ports correct? I wish for the physical ports to be trunk ports, So I guess I add vlan 100 to each interface then bridge the two vlan interfaces.

Is there a way to do it without creating a bridge group and adding the vlans to it?

I wish to be able to do it just like cisco etc an adding the same VID to multiple ports will allow those VID to be accessible on those interfaces.
