Description:
This article describes how to set up routing between a switch of the GS-3xxx series and a LANCOM router.
Requirements:
Scenario:
Procedure:
1) Configuring the routing features of the GS-3xxx series switch:
1.1) In your browser, open the configuration for the GS-3xxx and navigate to the menu item System → IP Address → Advanced Settings.
1.2) In the Advanced Settings, modify the following parameters:
You can add additional DNS servers if required. |
1.3) For the IP Interfaces, modify the following parameters:
1.4) If the DHCP client is enabled (the default ex-factory setting), the switch automatically creates a default route (network 0.0.0.0, mask length 0) to the standard gateway (in this example 192.168.45.254). The entry is retained when changing to a fixed IP address.
This scenario does not require a separate routing entry to be created for the network 192.168.0.0/24 because the packets are sent to the LANCOM router via the default route.
If there is no default route, it has to be created manually. |
If the destination network 192.168.0.0/24 is reached behind a router that is not the standard gateway, a separate routing entry needs to be created using the button Add Route.
|
1.5) Click on Apply so that the switch activates your changes.
The switch will now change its IP address and can be reached at the IP addresses stored in step 1.3.
1.6) Save the configuration as the startup configuration by clicking the red floppy disk icon at top-right.
Alternatively, you can save the configuration as the startup configuration in the menu Maintenance → Configuration → Save Startup-config under File name by marking the item startup-config and then clicking Save Configuration.
When the switch is started, it will load the startup configuration. If none is available, the default configuration will be loaded and the switch starts in its factory state. |
1.7) The GS-3xxx has now been configured.
2) Configuring the routing entries on the LANCOM router:
The LANCOM router needs to be able to send packets to the networks 192.168.50.0/24 and 192.168.55.0/24 on the GS-3xxx switch, and these are made known by means of routing entries.
2.1) Open the configuration of the router in LANconfig and switch to the menu item IP router → Routing → IPv4 routing table.
2.2) Click on Add to create a new routing entry for the destination network 192.168.50.0/24.
2.3) Change the following parameters:
2.4) Create another routing entry for the network 192.168.55.0/24.
2.5) The routing entries should then look like this.
2.6) This concludes the configuration of the RADIUS server on the router. Write the configuration back to the router.
3) Preventing communications between the different networks on GS-3xxx series switches (optional):
If necessary, you can prevent communication between the different networks on the GS-3xxx.
