Implementing VLans

RouterOS General
1

I red a lot about VLANs cause a colleague of mine is setting VLANs in Mikrotik in a different way than I do
Both ways work well, but what is best?

lest say we have 3 PCs connected to each of two mikrotiks (conected each other ether by ether 5) and three VLANS going over the net

Pc1.1 - ether 1 (Mk1)
Pc2.1 - ether 2 (Mk1)
Pc3.1 - ether 3 (Mk1)
Pc1.2 - ether 1 (Mk2)
… u get the idea
MK1 - MK2 (ether 5)

My vision about the things

  1. create 3 Vlans on ether 5
  • Vlan1-Eth5 id-1
  • Vlan2-Eth5 id-2
  • Vlan3-Eth5 id-3
    2.create 3 Bridges
    -Br1 (Vlan1-Eth5, ether1)
    -Br2 …
    -Br3 …
    The same to Mk2
    and we have
    Pc1.1 and Pc1.2 in Vlan1
    Pc2.1 and Pc2.2 in Vlan2
    Pc3.1 and Pc3.2 in Vlan3

Works!!!

My colleague
In Mk1

  1. Create bridge Br-trunk and put ether 5
  2. Create vlan:
  • with name Br-trunk-Vlan1 id 1 interface Br-trunk
  • with name Br-trunk-Vlan2 id 2 interface Br-trunk
  • …3
  1. Now create 3 new bridges
  • Br1 (Br-trunk-Vlan1, ether1)
  • Br2 (Br-trunk-Vlan2, ether2)
    …3
    The same to Mk2
    and we have
    Pc1.1 and Pc1.2 in Vlan1
    Pc2.1 and Pc2.2 in Vlan2
    Pc3.1 and Pc3.2 in Vlan3

Works!!!

For him, he say it is really easy to add another trunk port to Mikrotik1 or 2, just etherX in “Br-Trunk” bridge
For me I will have to add three new VLANS to etherX like “Vlan1-EthX” id-1, for 2 and 3 and put them in the 3 bridges : Br1,2,3

I can see the logic in both ways, where is the difference… which is working better taking in mind resources like CPU calculations…

One of my favorite things about MikroTik is all the different ways you can accomplish something. Sometimes, the situation will not allow you to do it the way you always did before. I don’t know which of these ways is the best. I have always done it the same way you described, however, I am going to try it the other way because I can see how that might be advantageous too :smiley:
