VLAN example on MikroTik Routers

VLAN example on MikroTik Routers - Let us assume that we have two or more MikroTik RouterOS routers connected with hub. Interfaces to the physical network, where the VLAN is to be created is ether1 for all them (it is needed only for example simplification, it is NOT a must).

To connect computers through VLAN they must be connected physically and unique IP addresses should be assigned them so that they could ping each other. Then on each of them the VLAN interface should be created:



[admin@MikroTik] interface vlan> add name=test vlan-id=32 interface=ether1
[admin@MikroTik] interface vlan> print
Flags: X - disabled, R - running
#   NAME   MTU     ARP       VLAN-ID  INTERFACE
0 R test   1500    enabled   32       ether1
[admin@MikroTik] interface vlan>


If the interface were succesfully created, both of them will be running. If computer are connected incorectly (through network device thet does not retransmitt or forward VLAN packets), either both or one of the interface will not be running.

When the interface is running, IP addresses can be assigned to the VLAN interface.

On the Router 1:

[admin@MikroTik] ip address> add address=10.10.10.1/24 interface=test
[admin@MikroTik] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
#    ADDRESS          NETWORK    BROADCAST     INTERFACE
0    10.0.0.204/24    10.0.0.0   10.0.0.255    ether1
1    10.20.0.1/24     10.20.0.0  10.20.0.255   pc1
2    10.10.10.1/24    10.10.10.0 10.10.10.255  test
[admin@MikroTik] ip address>


On Router 2:


[admin@MikroTik] ip address> add address=10.10.10.2/24 interface=test
[admin@MikroTik] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
#    ADDRESS          NETWORK    BROADCAST     INTERFACE
0    10.0.0.201/24    10.0.0.0   10.0.0.255    ether1
1    10.10.10.2/24    10.10.10.0 10.10.10.255  test
[admin@MikroTik] ip address>


If it set up correctly, then it is possible to ping Router 2 from Router 1 and vice versa:

[admin@MikroTik] ip address> /ping 10.10.10.1
10.10.10.1 64 byte pong: ttl=255 time=3 ms
10.10.10.1 64 byte pong: ttl=255 time=4 ms
10.10.10.1 64 byte pong: ttl=255 time=10 ms
10.10.10.1 64 byte pong: ttl=255 time=5 ms
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 3/10.5/10 ms
[admin@MikroTik] ip address> /ping 10.10.10.2
10.10.10.2 64 byte pong: ttl=255 time=10 ms
10.10.10.2 64 byte pong: ttl=255 time=11 ms
10.10.10.2 64 byte pong: ttl=255 time=10 ms
10.10.10.2 64 byte pong: ttl=255 time=13 ms
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 10/11/13 ms
[admin@MikroTik] ip address>
