==Configuring Routers==
==Configuring Routers==
We will not go too deep into basics. Assuming we already have VLANs set up to have three different links between routers according to the topology as well as failover between them enabled, we can jump straight into configuring dynamic routes using OSPF.

OSPF can be configured in WebUI, by navigating to Network > Routing > Dynamic Routing > OSPF.

If everything was set up correctly, we should see routes to the second network through the main link in the routing table:

Let us simulate Main link failure by disconnecting the cable and see how that affects routes to the second network:

As we can see, dynamic routing automatically switched to the next available route.

Let us connect a LAN device to each of the routers and see if they can communicate with each other, for this example, we will connect a laptop to the first router and RUT240 to the second router:
Let us connect a LAN device to each of the routers and see if they can communicate with each other, for this example, we will connect laptop to the first router and another laptop to the second router:
*Laptop IP: 192.168.1.220
* Laptop 1 IP: 192.168.1.220
*RUT240 IP: 192.168.2.5
*Laptop 2 IP: 192.168.2.5
Let us run a ping command from the first laptop to the second and disconnect the Main link cable midway through:

We can see that after a short delay, laptop on the second router continued communication, which means dynamic routes are being set correctly.
