This article will look at inter-VLAN routing on our XS3800, XGS4700 and other L3 switches
As for our scenario, we want to reduce traffic to the Security Gateway and use the XS3800 as a router for the inter-VLAN traffic.
First, we need to add the VLAN to the Security Gateway.
Configuration > Network > Interface > VLAN > Add
Now we add the same VLANs on the Switch.
SWITCHING > VLAN > VLAN Setup > Static VLAN
Then we need to give the Switch an IP in each of those VLANs
SYSTEM > IP Setup > IP Setup
Then go to Management IP Address and add your VLANs to the Management IP Address Records.
Next, we need to change the default router/default gateway for the Network clients
Configuration > Network > Interface > VLAN > Edit
The Network clients now use the switch as a gateway/router.
