In this scenario, we need to re-IP an administrative network, specifically a switch from the 192.168.3.254/24 network to 192.168.1.0/24 network. For the example, our switch has an IP on VLAN1 of 192.168.3.112. The default-gateway command is pointing to 192.168.3.254 would like to re-IP the switch to 192.168.1.5/24 with the gateway of 192.168.1.254 on another network…

If separate VLANs are implemented on a switch, then a router is required to provide communication between VLANs. Switch works at OSI layer 2 so it uses only Ethernet header to forward and does not check IP header. For this reason we must use the router that is working as a gateway for each VLAN.…

Original 802.1Q allows only one vlan header, Q-in-Q on the other hand allows two or more vlan headers. In RouterOS Q-in-Q can be configured by adding one vlan interface over another. Example: /interface vlan add name=vlan1 vlan-id=11 interface=ether1 add name=vlan2 vlan-id=12 interface=vlan1 If any packet is sent over ‘vlan2′ interface, two vlan tags will be…

Add necessary VLAN interfaces on ethernet interface to make it as a VLAN trunk port. /interface vlan add interface=ether2 name=eth2-vlan200 vlan-id=200 add interface=ether2 name=eth2-vlan300 vlan-id=300 add interface=ether2 name=eth2-vlan400 vlan-id=400 Add bridges for each VLAN /interface bridge add name=bridge-vlan200 add name=bridge-vlan300 add name=bridge-vlan400 Add VLAN interfaces to their corresponding bridges and ethernet interfaces where untagged traffic…
