Vlan between Cisco and Mikrotik

RouterOS General
1

Hello everyone ,

I really really need your help

I have a Mikrotik router with an interface connected to a Cisco switch
the interface between the Mikrotik and switch has two IP addresses 2.2.2.1/24 and 192.168.102.1/24
This switch has two VLANS 102 and 2004

I don’t know how connect those two together ? the other side of the switch has Cisco router with router on a stick for the same network 2.2.2.2/24 and 192.168.102.2/24

but when I configure the port on Cisco switch to access vlan 2004 then the Cisco router can’t see the IP 192.168.102.1/24 on the Mikrotik

2.2.2.0/24 for VLAN 2004
192.168.102.0/24 VLAN 102

Which configurations do I need for both Cisco switch and Mikrotik interface with the Switch


Please I need your help

Best Regards

You can go through this tutorial to get idea about how VLANs are configured on Mikrotik. You did not mention which particular MT device type you’re trying to configure so it might be that the way of configuring explained in linked tutorial will not be the fastest one, most of MT devices support VLANs in hardware (but configuration is different and details depend on device type).

I have this model mikrotik rb951ui-2hnd

My problem is that I have two Ips on the same interface on MT and I need to pass two Vlans to Cisco switch on the same interface

For starters, follow the guide I linked. Your device has a fairly nice switch chip built in and you can change the setup later on to facilitate switch chip functionality if the performance of RB951U will not be good enough.

Ok but please can you tell me the at least the Idea how can I pass two VLANS through one interface on MT ?!!

I mean like tips and if you have any information which command I have to use on Cisco switch I’ve just used to be Trunk

Just configure multiple tagged VLANs on single port … that’s what trunk port is all about. And such concepts are mentioned (if not explained) in linked tutorial.
