VLAN Encapsulation

RouterOS Beginner Basics
1

Hey guys,

I’m pretty new to routing & Mikrotiks. I’ve installed a few of them as the routers for fibre connections and all have been pretty straight forward. We have a new client that has a different ISP than we normally use, and the Mikrotik won’t connect to their service. We’ve been advised that they require us to set: vlan encapsulation 10
Can someone explain to me where I do this?
And what does this actually mean? Is it normal to need to edit this setting?

Thanks for your help.

Mikrotik support only 802.11Q encapsulation (STANDARD!!!)

Simply ad new WLAN from Winbox on interface connected with ISP with VLAN ID 10 and you obtain another interface to use.

MikroTik NOT (actually) support Cisco Encapsulation Inter-Switch Link (ISL), another method.

Here’s a start: http://wiki.mikrotik.com/wiki/Vlans_on_Mikrotik_environment

And what does this actually mean?

It means they are trunking the interface to you. Which means they want to segment another network or service on the same physical interface.

Is it normal to need to edit this setting?

It depends on what you mean by normal. VLAN is a standards based method for segmenting large broadcasts within a LAN and trunking is how you do it on a single physical segment. So, if you are needing to trunk then, this requirement is normal. If it were me, I’d ask what the other VLANs on that segment is used for and determine if it is required for your situation. If not required, then I’d ask for an access port vs trunked.

Hi rextended,

Thanks for your reply. Do you mean a new VLAN to the interface?

  1. Select Interfaces in Winbox
  2. Right Click the ISP (Fibre) interface and select Add → VLAN
  3. Give the VLAN a name, edit the VLAN ID to make it 10.
  4. Hit apply and OK.

Is that all - that will get it all going?
Thanks again.

Yeah… that will put a VLAN with ID 10 on that connection. You will have to update things like DHCP client, firewall, etc… as your incoming connection is now the VLAN interface and not the eth/fiber. Depending on the routerboard you have you may also be able to do some of it in the switch chip directly.
