Connecting CISCO Switch VLANs with Mikrotik Router

RouterOS Scripting
1

Dear all,
I already have two VLANs that created using CISCO Catalyst 2950 Switch.
But my company is planning to migrating using Mikrotik Routers due to bandwidth and policy.

My problem is, I don’t know how to use the current route the VLANs (CISCO Switch) with Mikrotik Router. I found that Mikrotik Router not able to perform this action. Correct me if I’m wrong.

Thank you for your help..

Hi,

This works fine.

I do not understand this sentence. The interconnection between the catalyst and
the MT is easy. Create a Trunkport on the catalyst and create the vlans with
winbox using “add vlan” in the interface window. Then you have additional interfaces
you can work on like normal interfaces.

:laughing: Sorry, but what I mean is..

I already have VLANs that has been created on CISCO Switches.
What I need to know is how to route the VLANs, so they can communicating using the MT.

And is it possible if I use two routers (MT Router) and both are using NAT, the local network of each router can communicate over the network.
Router A (with NAT) ======== Local Area Network A
||
||
||
Router B (with NAT) ======== Local Area Network B

My office are really killing me this time.. :frowning:
They always giving me a hard time..

Hi Peter,

  1. Create a Trunking Port on one of the switches and plug in one of the ethernet ports
    of the MT.

  2. Add the vlans on the MT using Winbox in the Interface-Window. For each vlan you add
    you get an additional interface.

  3. Add an IP on the MT for each Vlan which should be routed over this MT.

  4. Ensure that the IP-Devices have proper Routes (normaly its the default/standard-route)
    to the MT on the Vlan the Device is connected to.

This is a strange situation. Why do you want to NAT between RouterA and RouterB?
LAN A is seen on Router B as one IP so you have to do reverse NAT to get
connections through. Same on Router A.

So just do normal routing and you have a simple config.
