« Mikrotik : Tunnel GRE » : différence entre les versions

Dernière version du 19 février 2025 à 14:01

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:

`/interface gre add name=myGre` `remote-address=192.168.90.1` `local-address=192.168.80.1`

A router on site 2:

`/interface gre add name=myGre` `remote-address=192.168.80.1` `local-address=192.168.90.1`

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:

`/ip address add address=172.16.1.1/30` `interface=myGre` `/ip route add dst-address=10.1.202.0/24` `gateway=172.16.1.2`

A router on site 2:

`/ip address add address=172.16.1.2/30` `interface=myGre` `/ip route add dst-address=10.1.101.0/24` `gateway=172.16.1.1`

At this point, both sites have Layer 3 connectivity over the GRE tunnel.
