Application Example
VLAN example on MikroTik Routers
Let us assume that we have two or more MikroTik RouterOS routers connected with a hub.
Interfaces to the physical network, where VLAN is to be created is ether1 for all of 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 interfaces were successfully created, both of them will be running. If computers are
connected incorrectly (through network device that does not retransmit or forward VLAN packets),
either both or one of the interfaces will not be running.
When the interface is running, IP addresses can be assigned to the VLAN interfaces.
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
#

10.10.10.0

[admin@MikroTik] ip address>
On the 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
#

[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>
