We have two sites, '''Site1''' with local network range 10.1.101.0/24 and '''Site2''' with local network range 10.1.202.0/24. | |||
The first step is to create GRE tunnels. A router on site 1: | |||
{| class="wikitable" | |||
|<code>/interface gre add name=myGre</code> <code>remote-address=192.168.90.1</code> <code>local-address=192.168.80.1</code> | |||
|} | |||
A router on site 2: | |||
{| class="wikitable" | |||
|<code>/interface gre add name=myGre</code> <code>remote-address=192.168.80.1</code> <code>local-address=192.168.90.1</code> | |||
|} | |||
As you can see tunnel configuration is quite simple. | |||
In this example, a keepalive is not configured, so tunnel interface will have a '''running''' flag even if remote tunnel end is not reachable | |||
Now we just need to set up tunnel addresses and proper routing. A router on site 1: | |||
{| class="wikitable" | |||
|<code>/ip address add address=172.16.1.1/30</code> <code>interface=myGre</code> | |||
<code>/ip route add dst-address=10.1.202.0/24</code> <code>gateway=172.16.1.2</code> | |||
|} | |||
A router on site 2: | |||
{| class="wikitable" | |||
|<code>/ip address add address=172.16.1.2/30</code> <code>interface=myGre</code> | |||
<code>/ip route add dst-address=10.1.101.0/24</code> <code>gateway=172.16.1.1</code> | |||
|} | |||
At this point, both sites have Layer 3 connectivity over the GRE tunnel. | |||
