Multiple VLan's across a PtP Wireless Link

RouterOS Wireless Networking

I’m having issues getting multiple VLan’s across a wireless link, so I need the Guru’s of MikroTik to help me!!

I have tried to use the configuration from the link below, but could never get WDS to start on the Virtual AP’s.

http://wiki.mikrotik.com/wiki/802.1q_Trunk_extension_over_Wireless_P2P_Link

If someone has a better way to carry VLan’s across I’m all open ears.

I have uploaded a design of the network, and I’ll try to give as much details as I can.

Cisco Switch-1 Port G1
Tagged VL5,VL411, & VL525

Port G1 goes to ether1 of RB711-1
RB711-1 to RB711-2 NV2 configuration
RB711-1 and RB711-2 requirements (That they get an IP address from VL5) for management
RB711-2 ether1 to Port G2 of Cisco Switch-2
Port G2 is Tagged VL5,VL411, & VL525
Cisco Switches use VL5 for management
Video server port is Untagged VL525 from Cisco Switch-2
Wi-Fi Router is Untagged VL411from Cisco Switch-2


Any help would be great,

Thanks.

After reading more on the Forum, I found that MikroTik doesn’t support VAP and NV2.
This might be the issue on why I couldn’t get things to work.

So my next question is can you have a NV2 link and carry VLans across it?

I like the speed of the NV2 link but I need my VLans to get across also.

Any help would be great,

Thanks.

It doesn’t support VirtualAPs but that has nothing to do with VLANs. Post your config of each side of your link with /export compact

I turned off everything and went back to basics.

What I found was to move my VLans over to the WDS1 after I got the wireless up and running.

The biggest issue right now is that I’m not getting an IP address to manage these units to work.

I would like to use VLan 5 as my management but also I need to carry it over the wireless.

Not sure if that can be done or not.

Any ideas??

Thanks.

I have VLan’s that carry across the wireless network to my other switch, and I can get my DHCP IP address for each VLan Network.

I moved my VLan’s back to ether1 of the wireless units which were on the WDS before in the Config I uploaded. Both worked for carrying my VLans.

Great!!!


Now my only problem is getting IP addresses for the Wireless units themselves.

My VLan of choice is VLan5, but all I get is a DHCP offer that times out in 30 seconds.

I tried putting DHCP client on VLan5; Nothing.
I tried on ether1 with a PVID of 5; Nothing.

I have a Bridge between ether1 and WDS1 which carries my VLans across the wireless network.

Can I make another Bridge between ether1 and VLan5 so I can get an IP address??

Or will I create a traffic storm on my network?

Any help would be great.

Thanks.

Ok, I got it all figured out!!

I made it over complicated which is the reason I had issues.

Here is some info for anyone, that has a simular issue.

AP Bridge Wireless – > < – Station WDS Wireless

Bridge ether1 and wds1 → ← Bridge ether1 and WLan

DHCP Client on Bridges

Your switches

Tag any VLans you want on both sides.

If you have a management VLan for your wireless and switches which mine was VLan 5, you use UnTag VLan 5 with a PVID of 5 on your switch port.

I got IP addresses for my wireless devices plus my switch on the other side of the wireless link.


Hope this helps.

Hi… I am in dire need of similar solution.

One Wireless bridge using SXT 5 on either side each plugged into an Cisco Switch.

Multiple Vlans in network (201, 202, 203 etc.) Need to communicate with each other.

Currently only the VLAN whose IP is with the SXT device can talk. Other Vlans cannot talk to each other neither can those VLAN ping the SXT IP.

Please can you give a example of the config you have working…

You can transport VLANs over NV2 using an EOIP interface.

ETH-(bridge)->EOIP-(IP)->NV2 ~~ / ~~ NV2-(IP)->EOIP-(bridge)->ETH

http://wiki.mikrotik.com/wiki/Manual:Interface/EoIP

Don’t bother encrypting the EOIP link as it’s redundant if you are already encrypting NV2.

Of course make sure your switch is set up to accept all the required VLAN tags on the connected port.

actually i am having issues with set up to accept all the required VLAN tags on the connected port.

how to do that with a mikrotik device in PTP configuration?

hi… thanks for the update.

there are 2 things…

  1. the switches on both end (CISCO) are already configured and working with a cable in between. the wireless devices are for backup in case the wire breaks. as the switches are given and setup by a different vendor i have no access or control over it.

  2. my vlan id are as follows : VLAN200, VLAN300, VLAN400

can you please post a sample script with how can this be achieved with the above mentioned VLAN’s… with 2 SXT’s

help will be really grateful…
