RB/433 as client and VLAN.

RouterOS Wireless Networking

Dear All!
I have a couple of questions concerning the configuration of RB/433 (ver 5.11).
The situation is as follows:
We have come to one village with the wireless link from the town nearby. The scheme:
Edge Switch trunk with 3 VLANs — RB/411 Wireless <–wireless link—> village RB/433 with 2 wireless cards.
The task of RB/433, installed in the village, is to retransmit wirelessly 2 VLANs from the town switch to the end wireless user. The end user need to receive that 2 VLANs (one is for data, and one for voice), and terminate them on ethernet interfaces of the router (client RB/433). The first ethernet port of client RB/433 will be used for data, the second ether port - for voice device.
Recently I configured the village 2cards router: made both wireless cards as AP-bridge. And now the question:
How to properly configure the client’s router RB/433 in order to terminate 2 vlans on it?

Or more simply:
How can I make the ethernet ports as access ports (as I do while configuring Cisco swithes), and the wireless link as trunk port?

Hi sid! are you solved the problem? how to do an ethernet port of any RB like an vlan access port? i like to know this too :slight_smile:
Regards,

Yes, in theory I got it. It’s as simple as 2 mouse clicks. But tomorrow I will check my thoughts. I must create a VLAN, then tell the system to attach that VLAN to Eth0 for example. That’s all, I think. But once again I 'll check this tomorrow.

I have found the way of tagging packets. Read this topic:

Sure this will work for me, in an hour or two I will see it in practice.

No, that way was unsuccessfull. Still need help in configuration of the retranslator RB/433 and the user RB/433 to transit multiple VLANs and trminate them on the user’s ether1-3 on RB/433.
Recently drawn the scheme. And post it to the supportDOGmikrotik.com in a hope of the advice.

Yes, I have made it!!! Now I know how to push multiple VLANs through numerous Mikrotik devices and finally terminate them on RB/433, making it’s Ethernet ports as the access-ports in Cisco switches.
Al is as simple, as it can be (but very strange and perhaps complicated for newbuyers).
Steps, according to scheme, from left to right:

  1. Make trunk on the interface FastEthernet 0/24 of Cisco switch, and allow suitable VLANs on it.
  2. Mikrotik RB/411. Make it station-bridge. Write in the suitable frequency, make interface Bridge1, add 2 interfaces in it - Ether1 and Wlan1. This will be the bridge towards the retranslator.
  3. On the retranslator Mikrotik RB/433, make interface Bridge1, add 3 interfaces in it - Ether1, Wlan2 and Wlan1. Both of Wlans are made as AP-Bridge. Wlan1 is responsible for the trunk from the city switch, that’s why we choose in WDS tab WDS Mode dynamic, and WDS Default Bridge is Bridge1 . Wlan 2, which will receive the connections from local clients (Acces-point for them) is configured as follows: AP-Bridge, suitable frequency, (!) in WDS tab WDS Mode dynamic mesh, and WDS Default Bridge is Bridge1. The device will create dynamically the WDS subinterface for each client.
  4. The major config is in client RB/433. First, make interface Bridge1, add 1 interface in it, Wlan1. Then make interface ETher1 as access port for the VLAN XX:
  1. /interface vlan add name=vlanXX interface=Bridge1 vlan-id=XX
  2. /interface bridge add name=Bridge-vlanXX
  3. /interface bridge port add bridge=Bridge-vlanXX interface=Ether1
  4. /interface bridge port add bridge=Bridge-vlanXX interface=vlanXX
    And don’t forget that MTU for vlan is bigger than 1500, it’s 1522.
    That’s all. It started to work.
    Of course this is not the perfect decision, but IT WORKS. Any suggestions wellcome!

And of course, many-many thanks to http://www.sygard.no/ . That guys helped me to understand how to make Ethernet ports on RB/433 as access ports in cisco.
